Converter. Trans brake questions.

I do have a 2 step and line lock.

Are folks who use TB adjusting the 2 step for traction? Or do you just leave at full stall speed?
You can use a 2 step to a point. As soon as the 2 step releases it's gonna hit the stall speed immediately if you've got it floored. So a combo of rpm and throttle position. The same applies for footbreaking too.
