Reichard Pulley on A S-Trim

Whats up guys, I was wondering if anyone is running one of these ultra grip pullies on a S-Trim. They are pricey..but I'm in need of boost.
I run a 2.95/7.85 setup now...with a 7" crank waiting to go on.
I'm only seeing 9 or so #'s on a fully forged bottom end (not enough)
I only have minimal belt slippage so I don't wanna waste my cash.
I was thinking of going a tad smaller say 2.75 or something if I go with this pulley..I'm looking for 15#'s

I'm back in the states in 6 days so as Stiffler says

"It's on like Donkey Kong" ha ha

It'll be good to be back on the boards more often...and better than that back in the states!!
Can't wait to see the lil one and the wife.

Thanks anyways man!
