I suppose being 10 pounds lighter might make you fly .5" higher than my bulky 5"11 205 but "throwing the board" is easier as a lightweight? mmmm I'll most definitely disagree with that opinion.
By lightweight I mean having a higher muscle to body-frame weight ratio. All fat does is weigh you down and make each turn and movement take more effort - which ultimately limits what you can do.
