Viton will last longer. Other than that, there's no real difference that I know of.

I've had no problems with either one.

My choice would be viton... just because it is more resistive to chemicals and motor by products... but the item have lasted long time in these bikes...

thank you all. I'm going to keep a close eye on my oil consumption for a bit to see if I need to r and r the seals soon. for now compiling info.
blue smoke on heavy de-accel points me toward seals going bad.
