I love my twisted messes, but would agree after taking delivery of the Kennedy 24 I haven't looked at the twisted messes once
I also have a Twisted Messes Atty and a Kennedy 24, as well as 3x 2 post atty's (Petri, Hobo v3.1, Velocity [clone]). The Kennedy 24 is an absolute monster. I love the thing, however I don't use it in the same capacity I use my TM Atty in. I use my Kennedy 24 for normal builds - but for me, normal is fused Claptons. Right now I have 24/40g fused Claptons in there. I use my TM atty for my larger builds, like aliens, triple stagger fused, zipper Clapton helixes, etc. The TM atty fits pretty much anything I throw at it. The Kennedy 24 on the other hand would never fit the builds I put in my TM atty, first because of the post hole size, and secondly because it doesn't have a T center post block with 2 holes.
Each is great for their respective uses. I find flavor a bit better in the TM Atty, and the cloud production equal to the Kennedy 24. The Kennedy 24 doesn't leak unless dripped into the afc tubes or by overfilling the juice well as mentioned above.
I'm due for a rebuild in the K24, probably going to do it today, any suggestions for quads?
