So an update. I ended up going back to stock sliders for now. The JTK sliders started feeling much more wobbly, and keycaps would come off easily. I am thinking of purchasing a Realforce RGB and trying a slider swap with it. Will update with progress. The other thing I noticed after doing some research is that the stems on 6u spacebars (mx style) do not have a centered stab stem. So I am guessing you either have to purchase an alternative spacebar pack, or mod an existing stem to a 6u spacebar.
This is getting pretty expensive, and I am starting to wonder if sticking with PBT topre keycaps is just the best way to go here. I do have alot of sets though and want to be able to use them on this board...
