knifebright,
The easiest way, at this point, to have a tailstanding clickie on an Aleph light would be to use a black Z57 (Z62 I think /ubbthreads/images/graemlins/icon3.gif) and replace the stock boot retaining ring with a ring that extends beyoud the boot. It prevents the light from going off in you pocket and allows the light to stand on end.
I made a few of these in brass and they may still be floating around. I never did a bunch of them because it was cost prohibitive.
