which brand did you go wit hand how was your experience?

i ask thins because i went with one before, soon after i spun a rod bearing, my front 2 main bearings and front 2 rod bearings looked terrible
it was an asp...might have just been a fluke, but it had some vibration with it...
(weird because an lt1 isnt externally balanced in the front)

just asking yall to chime in quick...

May have been coincidental, BUT, I've heard few good things about them. U/D pullies and an E-WP are two things I would look past unless your dead set on having "full bolt-ons" ... The E-WP, I could see, but UD pullies gain little, and other than a select few, cause MORE vibration than stock.

I'm considering an ATI superdamper with 10% underdrive. Very expensive but I havn't really heard anything negative yet.

ATI is one of the few that makes a good UD pulley for our cars. The piggyback style ones are kinda "cheap" in my opinion.
