I've kind of lived out of my old Timbuk2. Great bag, holds a lot, not H2Oproof at all. Just got a BaileyWorks Super Pro and it's a huge upgrade. The strap adjustment mechanism is just great. Great fit for me at 6'4". Haven't really put it to much serious heavily loaded use yet, so I don't know how much of an improvement it will be from my Timbuk2 as far as riding fit goes, but it certainly is an improvement.
