I went with gripshifters. As many gears either way as I need. No time to twiddle my thumbs in urban South Florida traffic ( statistically most unsafe place to ride in the US). The Saint and Hone Rapid Rise both require hard to find 10mm through axles. The Hone hubs can be found cheap due to the unpopularity of this. The Saint hubs require their own larger centerlock brake spline so avoid those. The Zee is 10/11 speed clutch derailleur era so no Rapid Rise there AFIK. Plenty of LX,XT,XTR stuff out there. Most of the road series, Nexave, Tourney, 105 had it also.
I avoid trigger shifters with these because of the limited downshifting due to the reverse pattern.
I've used SRAM Rocket and Attack Shimano compatible twisters. But the spring load/ ratchet load is backwards to the derailleur spring. They mostly work, but upshift when wet can be difficult. The Ebike was 3x8 and now is 1x8. The Shimano 8 speed RR Revoshifters work well. But don't have the knobby grips that SRAM has, so they can get slippery also. But not as hopeless as the SRAM. Some people have used LH shifters on the right to get proper cable pull. I have a few of these but haven't tried it yet. Both my bikes are form early 2k era when gripshifts and Rapid Rise were popular. I found more reasons to keep it than to switch. But now that 'm running the even more ancient, and controversial front freewheel on both bikes most of the advantages of RR are already there. Except for downshift when stopped. One bike is now 1x11, and getting them both shifting in the same direction may be the deciding factor to move away form RR. Nothing to do with RR itself. But 20 years of shifting a certain way is hard to unlearn.
