Default Steel vs. Aluminum Pulleys

What kind of s/c pulleys do most of you guys run? I have an aluminum one and found out that it contributes more to belt slippage. Has anyone changed from aluminum to steel and seen a difference?

Interesting.
Can anyone else confirm if the pulley material should contribute to slippage?

how do you suppose it contributes to belt slippage? I've heard of the aluminum brackets flexing and switching to a steel one cured some problems on the ATI's but never heard of slippage cause of the pulley material. I run an aluminum pulley on my Vortech setup and I have no slippage but I do have an 8 rib setup.

I was told by Tony at UnderPressure that because aluminum is pourous the belt won't grip as good???
