Smaller belt is the cheaper route, but I'd go with a 100mm Aux. & a BF 2.76" upper pulley....or a 4# Metco lower with your current set-up! ...all cases you'd need a new belt!

I've read too many threads/articles about the stock tensioners being weak. Most seem to recommend replacing them. I know when I go for the pulley, I'll be replacing them all, too. Metco has a package I think, leaning that way. But yeah, I'd replace the others...
