My understanding is NHRA is under the impression that all (we) have to do is use an adjustable stop and we are compatible with tranny brake users with adjustable buttons (and a host of other tricky devices). That is incorrect because it also affects the hit on the slicks which can alter performance at the same time.
Hydraulic release mechanisms are known to be slower in release and can cause to much slippage of the disk and damage occurs.
The only thing that IS comparable to a tranny brake in Super Stock is a magnetic release as offered by Biondo. Apples to apples, both perform the same function with no advantages to either.

You got that right!!!!
