Thanks @west carven I played it in slo-mo and wondered more about the function of "rodeo arm". I'm beginning to think it is an overt sign of a very functional and deliberate transition in lower body direction at a time when the rider is unweighted. A feature, not a bug! I'm going to put my thoughts in the Rodeo arm thread. I learned other stuff from watching. Rider seems to be deliberately practicing a slarve entry into the turns, and clearly annoyed when he stuffs one up towards the end. Practice makes perfect.

Actually it's (tricky doing the acutes on my phone keyboard) Federation Internationale de Ski (FIS)

How long till it's an Olympic sailing event? Has speed, technology, & spectacle. I'd be surprised if it doesn't make it.

From the same session. A slo mo edit from a high def video on Vimeo (URL reference in video). Riders are named and nuances of style, and trunk and arm movement, can be seen.

Binding lift could achieve the same result without having to compromise boot fit. F2 standard wedges give about 4 degrees. Bomber TD bindings can have 6 degree cant discs. I have custom wedged the toe and heel pieces of my TD3s by an extra 3 degrees as part of experiments with 9 degrees of rear boot heel lift, and for combos of lift and cant for skwal riding.

For non-drone fliers, the pilot sees the course in that grainy, poorly tuned colour TV quality. The drone is as twitchy as anything and any manoeuvre requires adjustment of throttle, pitch, yaw, and roll axes, all while tracking the guy on the bike at speed. This nothing like flying a DJI Mini with inbuilt stabilisation.

Ever tried flying a drone in full acro mode with analogue FPV? Both the riding, and the flying, in a crowded, hazard strewn urban environment are mind boggling.

My original interest, and starting the discussion, was because in video of my own riding I had noticed a much less pronounced but similar motion of my outside/rear arm on heelside turns and was interested in understanding what was producing it. Thanks to all who have contributed so far, and to the poster of the original video. @west carven

Ash, above, has really nasty "Rodeo hand". @ 1:25 See below. Not meaning to cause offence. He (Ash) is having fun at that point in the video. His actual carving is stylish, powerful, and worth watching.

A trick to riding any board all day is to learn efficient technique, with good shock absorption through your knee and hip joints. That becomes energy saving riding, that allows lots of turns, lots of vertical metres (feet) and lots of fun. My aim is always weary legs by the end of the day, rather than being done by lunchtime. PS: I've ridden an MK. If I didn't have a KST 162 I probably own an MK.

Follows on from a short discussion of this in the Softboot carving worth watching thread. Watching videos in slow motion of carvers I suspect what is called "rodeo arm" is due to effective separation of trunk and lower body during a heel side turn. That is the lower body is driving the board into the turn and down and across the fall line. The rider's trunk is staying relatively close to it's orientation in the earlier part of the turn. The rider's arm appears to "flail" as the rider's trunk catches up with the lower body as the turn progresses. Most obvious on heelside because the rider is turning away from the relaxed trunk direction imposed by their stance across the board. Less or not obvious on toeside because turn direction and stance direction align. Most obvious on riders with pronounced cross board stances, still present but much less on riders with more forward facing stances. Interested to read others analysis and points of view. Added 8th May: Interested in part because I've seen a similar but smaller movement in my own arm in video of my heelside turns.

Does the front end tend to lift off uphill (saddle seems a long way back)? Or what is that on your seat?

No, but you do have to watch out for the cave trolls at the Weta workshop corner on the road route back to the top. It gets a lot of use, and many of New Zealand's native trees are evergreen, not deciduous.

Ragley Big Al 97.5er (mullet hardtail), 2.6" tyres with Tannus tube tyre armour running 12psi front and 18 psi rear, boost hubs, 4 pot Shimano brakes on 180mm discs, 1x11 with clip-in pedals, 120mm dropper, 35mm stem with 780mm handlebars. Jailbrake is a favourite trail about 4km from my garage door. Hardtails work your quads uphill and down.

Reloaded a backup copy I had of Ken's video to YouTube.

We are told the Contra sweet spot is high on edge. That tells you that the flex of the board is a very significant part of the shape of the curved path the board will follow. SCR is only a part of the story. The linked thread is a discussion of the interaction between SCR and long axis flex.

Straightliner!

We "crave the carve". I describe the sensation of a really carved turn as being as addictive as a drug. I can happily do the same run over and over, but I do seek out different lines to carve on that run. I enjoy runs with a variety of gradient. I love runs that have banked walls to carve on, and bottom turn on, and rise and fall and rise and fall. If I can't carve it, then the trail is just a means of getting to where I can. But that feeling of playing with gravity, that G-force pull as the board arcs across the fall line into and out of the turn. That is my drug, my addiction, my dopamine hit par excellence! --------------- I see powder so rarely that that is always an unfamiliar experience, where my brain is concentrating on just staying upright mostly. I have had moments where the board starts to float and flow and that playing with gravity feeling arrives.

Ikon pass website confirms price rise at end April 22. Just bought mine and given the choice of $Canadian vs $US. With the current conversion rates for $NZ buying in $Canadian was a significant saving. Trip is coming together. I should get to ride at Montucky Clear Cut 2023.

This thread should be pinned somewhere obvious. Mods - up to you!

Standard F2 thick/thin wedge set produces about 4 degrees of lift per binding. Both are needed to create the same slope on the heel and toe pieces of one binding. At binding angles around 60 degrees people whose body proportions are within 2SD of the mean generally don't need any canting, just front toe lift and rear heel lift. You may have already seen this video I made about the inter-relationship between rider physique, stance distance, binding angles, and how that affects the need for binding lift and canting. Heaven knows, I've linked it to a fair number of threads. https://youtu.be/mBTTJMo6Me4

Few things. If, like me, you lack lower back flexibility, then getting your bindings set to a position that leaves you with the maximum range of movement will make the most of what motion you have. Agree with NateW, you are likely to benefit from rotating your upper body to face the nose of the board more. Lastly, Larkspur is a relatively gentle run but, particularly on toeside turns later in the clip, your balance in the turn looks uncertain. Remember that in a turn you are balancing on the outside wall of the groove the board is cutting through the snow. That wall is directly underneath the lateral 1-2 inches of your board. Don't lean your upper body outside of that to initiate the turn. Stay balanced over that edge strip and tilt the board through both of your feet to make the turn. Then your balance will feel more secure.
