I did a lot of research and bought safecraft
I think its the best harness on the market with one exception
Its SFI but you get one free re cert from safecraft
The safecraft is the only harness with the adjuster that plugs directly into the center latch. It allows easy and fast adjustment with the best hardware I have ever seen on a harness.
Scroth is good too, but you can
still have issues with getting them tight and keeping them tight
