Default Which U/D pulley?

i know ive heard stories about some pullies throwing belts. Im going to bulk order a bunch of **** from tsp pretty soon and i was wondering which one was the "better" u/d pulley in terms of not having problems with it.

the asp or the powerbond? There is no ac in the car so obviously no AC belt

Throwing belts is a problem caused by not enough tension on the belt. I dont think that any of the underdrives actually cause the belt throwing problem at all. I added the Gates high wall pulley to my stock tensioner and have not thrown a belt since. I do not have an underdrive but I was throwing belts.

I think my problem was more the tensioner not the pulley, alot of guys have fixed the problem by replacing the tensioner with an adjustable one or just a new stock style, when I put on the high wall tensioner pulley it put a little more pressure on the belt and has the walls to keep the belt on. But really, the increased tension was the fix, I used to hear the belt squall between shifts because it was getting loose, after the pulley that stopped.
