I was out yesterday riding in the wind, uphill, and actually gaining speed from pulling on the upstroke. So for me, going uphill, in the wind shifting up, and a comfortable, proper fitting tight shoe made for an awesome ride!
To me, having an extremely stiff sole coupled with whatever attachment system is a winner-no matter who makes the attachment.
