I'd love to try taking the tip off of a 180/358 TTSX and seeing what it's like in my 356 LOL.

I don't generally get to hunt anything bigger than white tails and hogs, so a TTSX isn't really 'needed', at least in most stuff. I consider them added insurance in less powerful stuff like 223, 6.8, etc. I also shoot a lot of CNS on management hunts, where it really doesn't matter. That big HP in that 30-39 TSX seems to matter, but it's just anecdotal.
