Buy all picks would half to agree gearexpress.com, or mountain Gear.(Those are two places i purchased all of my climbing gear for many years.)But I Would use rei as a last resort if you have to or do a google search. But main key focal point is talk to the local team you will be working with and as others have said they to can give you more gear insight on what you will need and what you wont need. Plus down the road will save you money , for more technical personal gear later on down the road. good luck man keep us posted.
P.S cmc rescue is way to go.
