For the climbs you mentioned, I might also recommend LS Trango Cube. Its super light (under 3# for the pair), waterproof, and really comfortable - wider than their trail runners.
But - do note they are not full shank and do not have a toe welt. But again, for the routes you are looking at, you may not need it.
For a deeper review, you can see my review on Gear Junkie:

And for REI, just order them online and return what you didn't like. No fuss. Good customer service w/o the clerk BS.
