I haven't tested anything on scales yet, but I believe the weight rule will help bigger guys. I still think the 100lb kids have a great advantage, but I don't believe their advantage will be as great. In my mind, if everyone has to get up to 1350 to make the 640 rs rule, it evens things out a ton. I honestly think that 200+lb guys won't have to add any lead to get to the 640, if they do it'll be to make the 1300 pounds. I will say however that this gives guys much more incentive to buy light weight wheels!
