MRS for CFTBL whirlpool is a must. I used one many years ago and it was exactly what was needed. I loosened the tiltbob and could get the ball to make 15-20 rotations, besides it looking better. I didn’t buy them for RZ, as my leaf switches worked fine with some bending and there is a half-moon shaped leaf switch option available too. Now that I know you’ve fit a JJPOTC with a MRS, I’ll be ordering one as that seems like the right solution. Will get a spare one too and look for other applications to use.
