the whole 100lbs = .10 is 90% of the 60ft time… thats where it makes a big difference, now being this was a roll race yes weight in fact plays a big deal but not nearly as much as if it was from a dig… and you can have a car that weighs 500lbs if you trap @98 and the other weighs 8000lbs and he traps @110 he wins from a roll every time!!!
