Matt: I completely agree with you on Smartwool socks sucking! I'm actually mailing myself 2 more pairs in my supply box in Salida with plans to mail the 2 I'm starting with back to Smartwool to show them how bad their socks are. But durability aside, they are the only socks that actually keep my feet dry while doing any activity. I always buy them from REI so when they wear out too fast, I get a new pair.
The smaller Platy bottle is for drink mixes. I'm super anal about putting nothing but water in my water bladders.
As for the Pinnacle, I trimmed all of the straps, got rid of the ice axe stuff, and haul loop. I've actually thought about chopping the Z rest in half. But at the moment, I'm not sure the weight savings would be worth it. I've never slept on a half sleeping pad and/or used my pack backpad as a sleeping pad.
