I doubt an o-ring chain could be stronger, look at sidewinder's site, they claim the same strength rating on both the standrad and o-ring chains. When I replace my predators chain, I will definitely use one that is non o-ring, just for the fact that I hate messing with them stuping things every time the chain comes off, and I won't have to worry about using a o-ring safe lube. For maxium power transfer, non o-ring is the choice, with proper maintaince, it should last for quite some time.
