We're probably going to have to agree to disagree, because we're starting to go around in circles, which is exactly what happened in the thread about ankle "strength" and loosening laces. All I'm saying is that I think these examples illustrate that strength can't possibly be an important component of differences in stickhandling speed. This is 100% technique-dependent and 0% strength dependent. Advanced fast stickhandling is mostly about wrist roll, blade angle, and letting the puck slide out from the heel instead of lifting the blade over the puck on every pass. If anything, more efficient, high-level wrist-rolling probably takes less strength than inefficient lower-level, bottom-hand-dominant stickhandling.
