Went back to the local backpacking store today and drug both my parents with me. My dad still won't admit I'm know what I'm talking about, just that I've done some reading. The expert we were talking about was very impressed with what I knew about the Osprey Ariel, and was SUPER impressed when I said I was looking at a Tarptent. Apparently most people who go in there are completely clueless.
He also recommended looking at MSR, which I'll do here in a bit, and gave me some tips for training. Basically, vary the type of activity between walking, cycling and swimming, and make sure to stretch a lot, for at least 30 seconds each stretch. He said the stretching will really help for preventing and taking care of tendinitis. Also, I already read in the forums about putting your heavier items on top, but you should also pack them closer to your shoulders rather than the front of your pack.
Anything else general that you'd like to add?
