Who's running low 10s with leaf springs?

I've been running 10's with SS leafs and ladder bars and can't see any reason to change, unless I really want to lose weight to go sub 10's, which would require chassis certification. The car hooks with a vengeance and launches straight - who could ask for more ? Plainly put, it boils down to a weight to power equation; if you don't have the power to hit your target ET, loosing weight maybe the ticket. I really don't think it a matter of Cal Tracs VS leaf springs/ladder bars. Both have been shown to work well. Dan
