I'm 325 before I put my boots on. Tried all sorts of settings, baby bump, reversing side plates (bingham reccomended that one as they're slightly different lengths to the lower bollard position), bird flap from 4srt, nothing made the runner pleasant to break... BUT the zigzag chicanne combo is smooth as butter on any rope I've ever tried it on... only caveat is it wears pretty dang fast, so long decents I'll use a munter under it to take some of the friction
The hitch hiker 2 and mumfords new hitch hiker with the variable friction are also nice
