I use 808 threaded batteries that are similar to the Tritons. With an an 808 to Ego adapter and an 808 to 510 adapter I can use virtually any clearomizer I want.
I'm a big fan of the SmokTech Aro Pyrex but I also use a Protank and an Evod (not glass) on my 808 batteries.
If you're willing to pay the small price for a couple adapters and you don't mind the extra length they add to the set up you can use just about any glass clearomizer you want.
