I have similar taste in geo but I also like to run a gyro, which narrows frame choices down to like 3. Just now building up a bike after about a 3 year hiatus, surprised how much has changed.
its real simple to tap holes for gyro tabs and also if you're buying direct from fbm/etc they could do it.
Well, I have done it before with minimal tools and my threads were pretty shit, ended up just jb welding them in place on my 2nd wave. I'm sure with the right tools it is much easier though. Current build is an aitken s2 and that sucker has the tabs welded on!
