I have the cash to upgrade my hp and need some help. I would like to do compounds but don't wanna screw myself out of not being able to yank the sled. I searched NADM rules and the only info I could find was dated back from 2011 and it said I would have to pull in the "super street class." Searched that class and found very little info, so would I be better off going down the road of a single charger if I want to continue pulling?
