Pro tree braket race

I have to run 0.015 in the delay box. I can red light on a .400 pro tree. I was mainly just wanting to know if people enjoy braket racing on a pro tree. We run the 6.00 class on a .400 pro tree.
I have enough of a built in delay being 71 years old , boxes not allowed in pro dial or 11.50 index around here !
