  1. I rode the lift one day with a softbooter and he asked how long I'd been hardbooting and I told him about 30 years. He then asked "is it fun?" and my mind spin in many different directions I could go with that answer. After a long pause I said "no...not really" and the guy nodded in understanding. dave
  2. I’m sorry to hear that your board failed..but I’m happy to hear you weren’t hurt when it did. It looks like one of the very old foam core Rossignols and and they were very poorly designed and produced. I worked at a Rossi dealer back in the day and I think the only ones that didn’t fail where the ones that didn’t get ridden. Please consider yourself lucky to be uninjured and make a bench out of that thing. They never should have been sold to the public and you got much more mileage out of it than most did. You got lucky that both binding ripped out - that saved you from a likely injury. These boards failed when ridden hard because as the board flexes into an arc the binding can’t flex with it and the inserts will get pulled upward with a huge amount of force and they will fail. Modern boards are orders of magnitude better than your old Rossi…your riding will instantly improve, you’ll have more fun, you’ll smile more and you’ll be safer with a modern board. It’s a day and night difference. This would be very difficult to overstate. Have fun buying something modern. You will not regret it. dave
  3. I'm sorry that I didn't somehow see your post... The Oxess really does a great job of allowing for hard carving and powder floating in the same run . It doesn't carve as well as a narrow race board and it doesn't float as well as a powder board but it does both things well enough that I don't have FOMO for a different board that day...and its really fun! dave
  4. It's spring break week so we have some out-of-towners at Bridger Bowl. I was hardboot carving and riding single and shared a chair with a soft booter who looked to be in his late 20's. He looked down at my gear and blurted out - "dude! those boots are ****ed up!" I didn't know how to respond so I just said "thank you" and left it at that. He didn't utter single word after that. Awkward silence ensued. dave
  5. That is just the nature of spring steel...it will rust if left wet. I doubt titanium springs would be a viable answer. They wouldn't rust and they'd be a little lighter but titanium isn't nearly as stiff as steel (30% less stiff depending on the alloy) so the spring wire diameter would need to get a good bit thicker to have the same spring rate. New springs with a fresh finish would work or you could try getting them powder coated. Eventually any finish will fail and they will rust again. dave
  6. Interesting device. It looks like fun. With all due respect and then a bit more respect...why would someone choose the Oneski device over an alpine snowboard? Thanks so much. dave
  7. I use a Carveboard in the summer and the pneumatic tires are smooth and super grippy. They are a great size in that they are big enough to roll over stuff but not so tall that they get floppy when loaded up in a turn. You might check them out. dave
  8. Hello - This is Dave (tall guy, blue jacket) and I was one of Hing's fellow instructors (Andy, Hing and myself on the snow and Chester inside). I'll reach out to Hing and point him here and see if he can share the video is took at the MCC. dave
  9. For some reason the rear foot is carrying more weight than the front. It could be forward lean, it could be toe/heel lift combo, it could be technique, and it could be fore/aft position on the board. Assuming you have all the forward lean and toe/heel lift sorted you might try shifting your position rearward on the board by 10-15 mm. This will help you stay centered with equal weight on both feet while not feeling like you'll go over the handlebars unless you hold your weight rearward. I'll bet it would help. dave
  10. The year was 2002 and we got 58" overnight. The avy control was a huge task and in the end they couldn't open that day. The next night we got 10" on top of the 58" and they opened. You needed a big long stick and you needed to go as fast as possible to make sure you didn't bog on shallow slopes. It was fun but 18" is better than 60"+. dave
  11. I don't think that there is one perfect or ideal set up. I think there is a certain range that would work best and when getting too far outside that range things will start to get worse. I'm a bicycle framebuilder by profession and a lot of my time is spent designing a custom bike so that the person riding it is comfortable and efficient. There is no "one perfect" position on a bike but instead there is a fair narrow range that will work best for them...and within that range the small changes can help with comfort or power transmission. I think the snowboard is the same way. There are certain basic ergonomic things to keep in mind and they present a frame work to work in. If you get too far out of that (an extreme example would be duck stance on an alpine board) and while someone might be able to make it work they are swimming upstream and making life more difficult than it needs to be. So staying within the range will usually yield the best results. I hope that makes sense - it's late and it's been a long day so who knows! dave
  12. Should the set up be optimized for the static or dynamic? I'm not sure that they differ much. I think if you drop your hips straight down and the lifts and forward lean aren't good then you will end up moving forward/aft when you lower the hips...or you'll be weighting one toe or heel more than the other....or both. If your set up allows for you to lower your hips straight down and this results in even weighting/pressuring of the cuffs then you will have a very predictable and stable platform to balance on, and make power from. You'll still be able to adjust fore/aft as needed during the turn but it will be your choice and not one made for you by the set up. dave
  13. I use old raichle 125 (very soft) boots with BTS and very soft springs. I love them. dave
  14. A pair of F2's with the extra lift kit (they come with one and you need two) will be the cheapest, safest, and quickest way to get where you want to go. dave
  15. Yes...sole ramp angle does come into play here but unless your boots have WAY more than average I'll bet that you'll still benefit from have a heel lift in the rear just like nearly every world cup racer using Mountain Slope boots. The way to really tell how things will work is to follow the suggestions in my first post in this thread and play with different amounts of toe and heel lift and see how it feels on your kitchen floor. This can be harder than it may seem - you really need to open your mind to what your legs are telling you as you test different lifts on the floor. Feel how much weight each leg carries and how your shins are interacting with the boot cuff. When you have a good combo of lift (a gross adjustment) and forward lean (fine adjustment) you will feel the same pressure on the front of your shins against the boot cuff when you drop your hips straight down. The straight down thing being key. You can make lots of different (and not so good) adjustments feel like you have your shins pressing with equal force if you move fore/aft when you sink down. Drop straight down. You know you've nailed it when you sink dead straight down and the boot pressures feel the same. dave
