Looks like the new TVS are doing pretty good .

I need to re-read the MM&FF article with the KB vs TVS comparo'. It was a 2.8 to a 2.3 and the KB ended-up performing better under circumstances, but I don't recall exactly what. I know that at the end of the article I felt the test wasn't exactly objective but I'll report back after reading it again and getting a fresh take. Like you said though, it seems like these TVSs are doing well. In every test I've seen it doesn't seem like power is trailing off at the top end at all. On the LSA/LS9 peak power is reached at cuel cut-off and the curve isn't starting to flatten-out at all; similar to all these Maggy' tests.

Very encouraging

radz...what do you mean by: GMHTP & ARHs?
I'm sorry about that:
