SLK32 Crank vs. supercharger pulley

I already have an Evosport crank pulley kit on my SLK32 (came with the car.)

I'm getting a PSK from Needswings as a precaution, but I'm actually wondering if (in the long time) it's better to revert to stock pulleys and just go with a Eurocharged supercharger pulley?

Does anyone know if it's safer for the engine/pulleys to run a 61 or 65mm SC pulley instead of an Evosport (178, I think) crank pulley kit + Needswings pulley saver kit?

You will want the NeedsWings pulley wrap kit regardless of which pulley you go with or even keeping it stock.

Either pulley method has similar affect on blower. Crank method includes replacement water pump pulley to avoid issues there.

IMO a DIY'er can install the blower pulley while the crank pulley requires an ungodly amount of torque.

FWIW I have a ASP crank pulley and I had SpeedDriven put it on.

^ long have you had the pulley kit and what's your opinion on it? Also, did you make any cooling modifications or anything along with it?
