I have thought about this as well, I was thinking 7' 2", 20.25", 2.44" to take advantage of profile, tail width, bonzer channel, keeping it lively.thinking Varial and something like 7-4 x 20.75 x 2.56
With that said, you might want to consider a 8' 0", 21", 2.7" Twinsman Twinzer, which is one of my favorite boards, and highly recommend it. It is a bit different, fun challenge, gets you in early, and when you get your feet back it can move very well. It has a narrow tail and nose. Always a fun surf on it.
Since you have a range of boards already, and the midlength Plasmic is a bit of modified Townsend, this might be something different to try for you. If something happened to my 8' 0" TT, I would replace it immediately.
I saw somewhere on IG that Matt was surfing one recently.
