Suspension by WER?

Has anybody here had their suspension redone by WER? Works Enduro Rider

I know Go Race is the defacto WR² expert but just looking for other options. WER is local to me (I could actually drop off the bike or parts on my way to work) and they seem to get pretty positive reviews from people I've talked to who used them, but these were all KTM and Husky guys, don't know anyone who's had stock Yamaha parts reworked there offhand.

FWIW, I'm pretty happy with the way the fork behaves, but the rebound "damping" on the rear end is really starting to hold me back now in certain situations as I start to ride a bit more aggressively offroad. The way the back kicks up in whoops and over log crossings, small rock ledge jumps, etc. is unreal.

Not familiar with WER, but Go-Race replaces the seal head with a rebuildable KYB. Not sure what WER does. As far as I know there are no parts available for the original rear. I am VERY happy with my Go-Race rear.
