Couple of things on this. One is that a board that is manufactured with setback also is designed specifically for that and the binding reference points are matched with the flex of the board and the sidecut. There is a huge difference between a board designed to be ridden like this and just moving your bindings back on a board that is designed to have the bindings more centered. Sure, you can ride it and usually ride it just fine but it wont be quite as efficient and there will be some handling issues when you are not in deep powder.
Secondly, the retraction technique also works extremely well on a powder specific board with a lot of setback. It works amazingly well on a regular board too. Today, I was hitting deep (knee to waist deep) powder stashes and I am a 190 pound guy riding a 156 Gnu Billy Goat and never got stuck or took a single tomohawk.....
@ Bear5001, Along with the retraction at edge change, I have also been having great success with using retractions of the front foot like this even when not changing edges but when I feel the nose starting to get "sucked down". Today was a great example of this when I was riding in the great powder off of Vista. From a technical AASi standpoint, I am not sure is this is "correct" but it sure seemed to improve my powder riding and you know how deep some of those areas were (waits deep wind deposits and as I am sure you heard, several of us got first tracks on Cascade when they opened it up at 3:00. I made 3 runs before the 3:45 lineup. Would like to hear your thoughts about doing this the way I was today...
Nice! Forgot about this thread. I think that the board should still be balanced at the most setback position but you sure can feel the difference.
