Lefty Platform Damping Upgrade

Was talking with Aiden at RLCSport.com.au a couple of weeks ago and he mentioned that on the PBR Leftys they provide a tuning service to firm up the slow-speed damping circuit to limit the bob on out-of-saddle pedalling. Apparently they do it on all their race bikes.

Am thinking about getting it done on my hardtail, which needs to have a fork service. Just wondering if anybody has had this done and what they thought about the results?
