More thoughts...
My taste buds seems shot again... Can't taste flavor atm.
I like the T3 more and more.
I'm lazy with the airy draw, but quickly noticed that if I used my thumb for the battery button, my index finger could curl around an intake hole on the T3... Imagine a golf grip. Covering 1 of the 3 holes is just enough to make it excellent... If I manage to cover 2, the draw is very tight.
After vaping about 4-5 ml, I decided to take it apart to clean. Even if I couldn't swap out coil assemblies, I love the fact that you can dismantle to clean thoroughly. The post to the coil assembly was really tight. But once that was off, I could easily get at the coil and wicks. One of the wicks was coiled, the other two were just laying on top, and around the coil. I very carefully removed them to get a better look. All wicks seemed clean and no gunk on the coil at all. I just rinsed again, just in case, let it dry a little before reassembling. I use high PG, so I reassembled exactly as new. I've heard with high VG, reversing the rubber cover to the post, and/or removing 1 of the loose wicks helps too.
Huge step up from the x2 clearo which isn't designed to be taken apart.
If SI continues to sell the x2 clearo, I hope they upgrade to the newer version available which can be fully dismantled, just like a T3, except top coil. My x2's seem to be lasting well, so I shouldn't complain too much about it.
I hope SI continues to expand inventory...
I think multiple options on clearos is good. A large top coil and Large bottom coil clearo. I would ask for the T3 mini as well, but that would be greedy.
EDIT: OTOH, if SI is considering the T3 mini, stocking the coil would cover both products.

Also, if the mouth piece were made shorter, it would further reduce the size of the unit. I think
it is unnecesssarily long, even on the big T3... Sorry, couldn't help myself.
