yeah, think I'm going to try a stumpy too. I did tighten up the oring on the derringer with a bit of thread behind the oring and it's snug now but still seems to be easier to pop off because it's so shallow, the oring is only like a mm or 2 above the bottom of the deck so even a little movement and it just pops off, then the inner afc ring thing always pops off too, I really hate the derringer, would trade it for almost anything else at this point if anyone wants it, so I was very leary about trying the stumpy but seeing it has 2 orings I'm thinking it should be better and now with you guys endorsements I'm going to go for it.
ideally I love screw on caps the best. someone should make a tiny shallow thing like these but with a screw on cap and top air flow... the chalice III hits almost all the marks for me, only the airflow is a bit tight. I still like my modded chalice II the best out of everything, center Z coil and airflow from both sides, I drilled the other side open and made an afc ring for it, just like the stumpy in a lot of ways but even smaller... I think a combination of the stumpy and the C II would make an ideal atty, meet somewhere in the middle at say 18mm, screw on cap, center coil with dual airflow... hmmm, something similar to a nuppin but with screw on cap and dual posts.
been running my nuppins with a center coil and dual air and it's awesome, lately I only want to do single center coils on everything, I'm even converting a few other atties to dual post center coil setups too, converting a Quazar, an astro and an Origen v2 to dual posts....
ok, stupidest question of the thread, how many atties does one man really need? I know you guys are the wrong ones to ask here
