There are a bunch of people that would love to learn more, but you've got some secrets that you won't reveal. I'd love to hear some reasoning of how/why a clothoid curve works on a snowboard sidecut, but without the name-calling and extremely defensive posture. I for one don't understand how the rate of change of acceleration in a vehicle driving on a clothoid curve has anything to do with a snowboard that has a clothoid curve for a sidecut. The clothoid-shaped road presents a simple 2-D problem that relates to human sensitivity to sudden changes in acceleration, the clothoid sidecut on a snowboard is a 3-D problem with some pretty funky inputs with two highly variable discrete point loads (our feet), changing edge angle, a decambering board, and dynamically deforming snow underfoot.
I'm noticing this is a trend. You state something, when people question it at all, you call them idiots and leave the thread. It really leaves anyone questioning and the readers wondering if you really know something about this or are just an internet thug. Sorry, I hate to call you out as you obviously are quite intelligent but you're making claims that don't mesh with simple 2nd or 3rd year mechanical engineering principles.
Lets drop all the internet tough guy stuff and have a real discussion about how the physical design of snowboards affects our riding and enjoyment of the sport. I'd love to learn more!
