Huh, good to know - I've only been trying 70 durometer rings and 80 when I find I have them. I'll have to buy a bunch of 90's!
I'm going to be getting a CART reg + 12g changer this weekend. gonna try it with my old female stab once I get her rebuilt. hopefully that'll come closest to the original light design idea, cause as you said my CA setup sure dont!
again, much thanks woouulf! LOVE that (acidwash?) red thumper there
