Hey folk just wondering what a person should double up on for trad climbing in the jasper area in canada, (lost boys), (Juno), (Rock Gardens). I use BD C4's now. I was thinking doubles in 1,2, and 3's. Maybe a .75. And suggestions?

I haven't been to that area, but most of my need for doubles has been in the .50-2 range.....maybe 3's every once in a while but 3's+ I've rarely needed doubles of as I tend to stay away from larger cracks and concentrate on thinner face climbing. If you're doing cracks with hands/wide hands, the 3's would need doubled probably.
