I have a full Shimano drive train, but I don't want to mess with the connecting pins of the Shimano chains. I have not noticed the the Sram chain works any differently on the Shimano group. The Powerlock is different than the Powerlink. Rather than pull opposite directions on the chain with your hands to snap the link together, you push a pedal down and use the force of the crank to snap it in. Once its locked, its locked for good. I carry extra Powerlock links for emergency repairs. The weight savings of the hollow pins is minimal, but it does look pretty cool.
