Footbrake vs. Transbrake

With a 2 step, foot braking and line lock will a car hold at 3500 rpm or is it going to creep ?
Depends on the converter and also, if you are going to use line lock to hold the car at the line, then make it a 4 wheel line lock. That way you don't have to try and release the foot brake and line lock at the same time while trying to cut a light and stand on the skinny pedal.... lol
