Good morning, EC.
OTD, I've been using the T2 and Evod clearos. Both work well, hold a bit, and like hitt said, you just replace the center post with the coil in it instead of throwing the whole thing out. They twist right in. The evod will ONLY fit the outer Ego style threads on your twist battery, though. (no 510 connector on that one). Discount Vapors has some low prices on those.
Our last child moved out and we are renewing our house. We just remodeled our living room, flooring and all. I have been running 18 to 20 hour days for a couple weeks because I still had to work all of my regular jobs, but it was worth it. Next up is my daughter's room. It's going to be a sporting goods / office space. It would appear that the old dog has claimed my new chair.
