I think my issue is that I can unclip much easier and realiably twisting my heal inward towards the bike whereas I keep hearing that you have to unclip with heel going out away from the bike. When I had the tombay, I was trying to unclip with twisting the heel out,. I mentioned this to the LBS guy who was a racer in his youth and he stated that heel toward the bike is the only way he does it--heel out hurts his knee. Also, with the float, there is less to reach the unclipping going in--there is much more distance to reach the unclipping point going outward.
