Mod complete! It feels really really good! Hypersphere's rings are the real deal. The tactility of the *bump* is still there and I can feel no difference in actuation. And boy is this puppy quiet now! A total night and day difference. The HVAC in my office is already kind of loud so the stock thock was never an issue. But now I can hardly hear the thing. But I can still *feel* it.
Used Superlube oil for the slider rails and some extra thick lube on the stabs which I had lying around for my arcade stick. The stabilized keys feel really nice now and just as smooth as their unstabilized counterparts. I didn't put landing pads on the spacebar since sound wasn't a huge issue for me. Lubing seems to have helped it a lot though.
The entire mod took around 2 hours to complete and I think anybody with a little bit of experience opening things up and putting them back together can definitely achieve this mod. It wasn't scary at all. Though some parts did take a little bit of patience and care. That said, I wouldn't want to do this again anytime soon, but I think I will do this myself again rather than shelling out the extra dough for a Type-S.
Next on my list is getting a PBT spacebar. Anybody know a reliable place I can get one? Also if anybody who is interested in this mod has any questions, I'd be more than happy to answer.
