Adjustable Transbrake buttons for Bottom Bulb Racing ??

NHRA Division 1 is allowing transbrake, 2 steps , and air shifters this year. I have the air shifter and 2 step taken care of.

My question is about adjustable Transbrake buttons. I am looking at BIONDO - Terminator, or COLLECTOR TETHERS- Just-n-time. Anyone have any experience and or preference.

My car will go about .040 RED if I am leaving at the flash of the last yellow. Car is 1973 Dodge Dart sport, 540 cu. in. 727 3 speed auto, 4.10 gears. Torgue converter flashes to 5700. Usually 60 foot of 1.24 to 1.25 . Will carry front wheels out to about 50'.Best et 9.14 at 146 mph. Usually 9.20's et. We are freshening the engine now. will have a few more horsepower, guessing about 40 - 50 hp.

Trying to figure out what to order....
