60' and ET footbrake vs 2 step

Are you guys using an adjustable brake pressure switch? Are you adjusting RT with brake pressure? Launch RPM? Or both?

I have an adjustable brake pressure switch. It has separate adjustments for ?arming? the 2 step and ?releasing?. This can effect reaction time a little, but mostly I use RPM adjustments for R.T.

I’m new to 2steps (previously raced transbrake cars) not knowing where to start I’m at 2800 rpm using an electrical switch on the pedal. I see cars that roll forward before lifting the front tires and that would seem to be the best rather than picking them up out of the beam. I haven’t tried footbrake since the first two runs on the car. I’m also going to try and compare the difference. I have bias tires on the car now and 60’ 1.37-1.39 but plan on switching to radials. Is the leave comparable or am I going back to the beginning?
