When people start talking about how "little" something might be better or worse, I always reflect on this picture:
Somebody figure out how many watts, grams, or whatever made the difference between winning and not for me here. Then explain why we shouldn't sweat the small stuff.
The rub here is that mechanical watts are seldom considered in the equation, nor is stiffness. But can create a benefit or loss of net forward motion.
Pretty easy to drive yourself a bit bat**** crazy over this stuff but it can often be worth making your best educated guess on the best performing wheel for a particular course.
