Looking good! How's the height of the hybrid Jack when sitting on the Topre slider though (compared to stock row height)?
Always figured there would be issues with the depth of the top of the cap/stem length of MX-compatible caps when used with stock Topre- like the Topre slider would run into a stopping point sooner than normal, resulting in the cap sitting up higher. My guess was the only way to really make it all compatible was to cut down a stock Topre slider to something around Novatouch slider length, then using a TMX-esque stem, but I never got around to tinkering with it.
And ofc the reverse is if you use a full-length Topre stem as the TMX, then I figured it'd sit up higher on MX (with no easy fix).
