i use 9.5 tube for my downstems, never tried 12, so i couldnt tell u if its easier. it is important to make sure the glass is not too thick where you want the hole, i wouldnt worry about diffusing it until you get the hang of them. i flare the end of it, then just eyeball the length, keeping in mind it will drop deeper when you push it. i drop it in the can, with the flared end sitting on the lip, stick my reamer in it while i heat the flare with a small, sharp flame, the reamer holding it in place till it gets hot, then ensuring that it is sealed all the way around. next i take reamer out, and heat just the clear flared end of the downstem and reduce it till it is just about the size hole i want, then push with the tip in the hole. the first push i do just gets the flared part of the downstem flush with the can of the bubbler, then i can heat the rest of the bowl without closing the hole by not letting the flame hit the hole. sometimes it takes two or three pushes, better than trying to get it too hot at once and risk closing the hole. downstem should be straight from the tip of the push, if its not, i just put very little heat on the hole, insert tip, and spin to straighten. kinda diff tech than ur doing, hope it helps!!
