My personal recommendation is to go with the speed pros. They were the go to for many years, I haven’t seen many examples on here of them failing. Multiple local machine shops have said the KB Hypers have issues even when you open the rings up to their specs. The shops said you wanna go REALLY big on the gaps
Of note: KB’s website says they sit 0.025” under the deck. Quite a bit of deck to trim off
