I have side mounted pegs on my ruckus. i am use to riding sport bikes. not the same riding posture as a bicycle, but still hunched forward. the bag cradles my body nicely, and the over all fit is great. my qualms with the strap are not due to the fit, they are due to the lack of "on the go" adjustablity in the strap as well as lack of padding. I have a Chrome Metro, that is my main bag when i am on any of my bicycles, i use to use that bag all around, scooter, bike, walking around the city (i walk around Philly a lot and have done so with more bags, and styles of bags i can count) and the strap that hurt me the most was the R.E. Load. I can solve this by buying/making a pad, but for $300 I wish it came a little better equipped.

Quality wise, this thing is going to last me forever. This strap is never going to wear out, I can carry damn near everything in my apartment, and it is PA made. And the double outside pockets, are far superior to the small Chrome pockets. It could use a zipper pocket for the small things you don't want bouncing around, or lose.

edit: every one is going to have their own favorite bag. The best thing for you to do is sit down at your computer for an hour or two and read. Go to the different manufactures web sites, see what bag or bags have the options you are looking for and read reviews on them. See what bags hold up and how the comfort level fairs with each one.
