mine's been absolutely flawless as well. only had to bleed the system when i replaced the lever due to a crash (had a top mounted left lever; replaced with an under bar mount to fend off a repeat occurrence). love the thing; not a complaint to be had from me (i can't feel the wiggle on the bike).
Yeah if I go with the reverb I will get the right hand switch and mount it on the left upside down. I ride 1x right now anyway so I shift with the right, drop the seat with the left.
Is the reverb fairly straight-forward to install? I imagine it's pretty easy except for possibly the issue of shortening the hydraulic cable and bleeding the system but if the instructions are good and the equipment is all included then it should be not too bad.
