True, and had I had the ability to try on a ULA, I might have. Only packs that I had that were easy for me to get ahold of were Gregory's and Osprey's, unfortunately the Osprey's didn't fit me well, and at that point in my life I still had bulky equipment.
Actually, I'd thought about going to a smaller pack, but after my trip to the 4 peaks in AZ I decided that I'll take this behomoth with me for a month on the PCT, sure to get lots of weird looks.
In the end its still all personal preferences. Different packs for different backs.
