Changed my second PCB to also be HHKB like the one I've got rocking green Alps.
This one is using Brown linear Alps on the mods (backlit), and brown tactile Alps everywhere else.
Not sure how I feel about it, but these PBT caps from the IBM 5140 are sick (perfect for an HHKB layout). Mixed them together with my Dell AT101 caps for a complete layout. Don't have a beige space bar to really blend well with the bottom row.
Not using stabs on the enter or left shift keys, but Alps are pretty solid without stabilizers. I'm going to see what I can do to try and mod Cherry PCB stabs to take Alps plate mounted stabs. I know it can be done.
I'll give it a shot when things are more lax around here.
Also, not sure about these brown tactiles though. I can't imagine they feel like Topre (as some like to compare these to), but then I've never tried topre. Lubed ergos feel closer to a pleasant rubber dome than this does.

Backlighting is a little out of place with these traditional caps.
