I've ridden 19's for a year with no issues. I'm about 170 lbs, and the OP is 160. It's probably ok, especially if he's really only interested in the pursuit. That said, I think they are not any faster than 22's. There's no real advantage, methinks. I only bought 19's over 22's cuz they were on blow-out at PBK.com. Maybe they LOOK faster....
