which charger for less belt slippage

I haven't had any problems with belt slippage on the Vortech kits. ATI isn't to bad until you start to run more boost. You'll sometimes see a little slippage.

I could go on and on about slippage with a D-1 at 10+ psi.If I was going to go FI it would be a QMP turbo kit installed by them or a YS-trim supercharger like PSJ is doing.If you stay@ 8 psi or less the ATI is okay though.If you plan on making big power the ATI is best avoided.
I will do a t-76 QMP kit.......
My D-1SC setup should be pretty stout.....I'm running a bigger filter on the head unit, twin intercoolers help out, ATI race ready BOV, ASP 7.85" 8 rib crank pulley, 3.3" 8 rib ASP blower pulley, custom bracket support by chris sikora...
Its on a 6.0L 372 motor, shooting for 12-13psi...
The next step to make this setup go faster is to upgrade to an F-1 head unit and get a front mount intercooler, and I would have to get new pulleys for the F-1's ratio difference....
So I figure when that time comes, I will just sell the kit for a good price, there won't be that many miles on it, and then go and buy a turbo kit...
