I love MEC in general, but everytime I look at their pannier attachment system I cringe. I only use Ortlieb panniers because they have such an easy and secure attachment system. If MEC had equally good panniers I'd be using them. Last time I checked they were not even very cheap. For the money buy some Ortliebs from Wayne at the touring shop and don't worry about panniers for another 10 years +. Just MHO.
