Ex tracker here, same problem but i see u are in the fat side of the force dude, im like 5:11 and near 200 also and im big a$$ fat person No offense ok?

If the problem is rubbing or that the velcro tape thing that goes around the seat is killing your clothing (until now u said u are fed up with a problem but u havent mentioned the problem YET!) the solution is to put electrical tape around, no other way to avoid it, even if you lose weight the rubbing problem will persist.

What u can do is to find a pouch thing that hangs from the frame. Or, do not use the 2nd bottle and use the cage as a carrier stuff thingy and put a pouch in the second water cage, or put the stuff in your jersey.. u can't have it all
