Just be careful with the 510 connection on the aluminum model. My black beauty is already stripped out. Bummer too, cause it is sooooo lightweight.
Ya my aluminum is set up for stricktly dripping so there really isn't much need to be changing out atties. I stick with the A6 most of the time. You might wanna consider getting a black A6 and just keep them together, kinda like a Novice by Chris Creations. I did get another aluminum and will be getting 2 more and just doing the same with them, especially since the A6es are in the same color choices, they make a great lightweight stealth setup and really do luck bad*ss with matching drippers and tips. Like in the photos above (the stainless all matches anyway).
He's looking to get smok Kicklet clones in so even the aluminum ones can have kicks. smok just released them in a few colors and look pretty cool, just hope they will have gold, red, and black for my aluminum locks.
