I would leave the 3rd cim if you can make it fit. You never know.....
We've decided against 6 CIM because it draws too much power and we've never needed it.

If you could post that encoder mount that would be awesome! My team is skeptical about the encoder in axle style mount because of the way it's held down by the encoder wire.

I'm looking at the cad for the WCP SS gearbox, if you look on the back of the gearbox underneath the motors where the pancake piston would be if the gearbox were a DS model, you'll notice that there's a 1/4" hole in the back of the drive axle (if you haven't replaced it). There are also two holes flanking the drive axle. My thoughts on an encoder mount would be to 3D print some type of bracket to bolt into those flanking holes, and then have a face plate that the CTR encoder can bolt into. Keep in mind that the encoder shouldn't be loose, but the mount should have enough flex so that when the gearbox is under a normal amount of stress, the encoder isn't forced to also endure that stress and can move slightly.
