Great looking stuff -- before I get too excited, can you help me with a few questions? (1) what is the finished width of this set-up? (2) is the overall set-up symmetrical? if different (e.g. how far off - 2" wider on left)? (3) same as the two above if the kit was using 2 - 35L bags (4) what is the system weight (your rack and two panniers)? Thanks!
