I thought the best approach was to use the line-lock and shift manually 1-2-3, then roll out of it. But I was regularly going 6K+ even shifting quickly. The last time I left it in D and it didn't really make a difference with the RPM, other than shifting by itself into higher gears than 3rd. Seems like if I don't go WOT that the car gets bogged down too easily during the burnout and makes being consistent difficult.
The one advantage I've seen from not using the line lock (foot-braking the burnout) is it seems easier to keep the RPMs under control with that bit of extra drag from the rear brakes. But I don't want to toast the rear pads & rotors prematurely doing it that way.
