Wow.... I still don't see what the big deal is with this 100# wing. I made the exact same purchase when I was a newbie, and have had no problems. I tried the 45# and the 100# and the both felt the same. So, bigger is better in my mind.
Go with the 100#. Go with the cumberbun, and pockets, I love them. I just wish my wing was black and not red.
I dont use bungies, just because they look lame all bunched up. I just attatched the wing in a mannor that they kind of "Fold in" and is very low profile, and my wing doesnt flap in the wind.
Email me if you hae anyquestions on setup if you end up getting the 100#.
