Yeah, I'm just thinking KMC Kool's as it's pretty much the only chain I use. Always use 3/32" these days because there's simply no point in me running the 1/8". 3 years?!! You're stupid brave aren't you?! I replace mine every 6 months or so just for peace of mind. Snapped a couple of chains 'back in the day' and now, for £6 a pop, it's not worth the risk to be honest.
