Erhoth. Did you swap tuners yet?
I asked about which tuners I should get to swap out of my Dub King a while ago on this thread, which didn't get any response here. I took it over to the Reverend forums, then to email to Ken Haas. He responded very quickly (thanks, KH!) with the info that he measured the posthole at 17mm - actually, that's a little tight for all the ultralites (Res-o-Lite, Hipshot). They want 18-19mm holes, according to the literature. This probably means keeping the stock ferrules, no big deal.
He is getting in touch with Brad Hauser to see which Hipshots he installed in his. When I get this information, you'll see it here. Personally, I'm leaning toward the Res-o-lites, but I can be dissuaded. I know BH likes his Hipshot Ultralites.
