I ran into a similar situation - the chain was old, but kept breaking...turns out I wasn't pushing the pins back in properly (SRAM PC series chain).
I don't like using SRAM PC chains. Recently, I've used a KMC X10-EL (so not 11sp, solid pins hollow links) for 700km in dry dusty conditions, lubed about every 150km. Didn't miss a beat. I assume their KMC X11-EL is similar. I would step down to a non-hollow plate chain in wet conditions, purely as the hollowed out parts of chains pick up lots of dirt with wet lube...I cursed myself every day I was running an X11-SL (hollow pin, hollow plate) on my roadie in winter.
