Since I could only vote for one, I went with the 49-way.
I would probably buy them for my T-stiks at some point, but would really like to see them released to fit NOS Wicos.
If you do release them for the T-stiks, I think they should be a little taller than the tall balltops that Andy has.
I think I'm the only one in the world that actually LIKES the T-stiks mounted under a 3/4" wood panel without routing, and that's only because I played so much Crazy Climber (with its knuckle dragging short sticks) when I was younger.
