I know this is short notice, but I am looking for anybody's quick input as I got the go-ahead to drive out to REI tomorrow (over an hour away) and get my first backpack. I am looking at the following and would love any comments about durability, quality, best value for price, etc. Looking to start section hiking this summer, first trip planned for Georgia in August. Wanting to spend between $185-$240 and get a pack that is reasonably light and good for 5-7 day hike. Posted earlier in general gear thread on a specific pack and got great info. Thanks to all who can reply promptly, really appreciate it.

Looking specifically at these packs:

REI Flash 65
REI Crestrail 70
Gregory Z65
Osprey Atmos 65
Deuter Aircontact 65+10

TIA, DarkBunny
