I got two 300 mile days this weekend through South Louisiana to test the new gear.
The added padding and leveling of the seat solved 90% of my reda$$ issues. I also do not have burning quads from continually repositioning. The extra 1/2-3/4"thickness reduced the locked knee circulation issues.
The SW-Motech rack with the cheap JC Whitney top box was nice for the capacity.
There is one issue with the rack. Since it cantilevers out, it is a springboard. In transit, it inverted the contents of the topbox from continual bouncing. I didn't get a multipoint rack since I didn't think that I needed the capacity, but I'll probably have to beef it up so it doesn't shake to destruction. I wouldn't recommend this rack, if I were to do it over, I would get one that is triangulated better.
All the suspension work was worth every penny.
