Default Transbrake launch rpm?

I was wondering what rpm's to launch off a transbrake. High or low? ATI states to go as low as possible without the car hesitating and that will produce the best times. Just curious to know what you guys have found. Maybe post some stall speeds and launch rpms.

Have you ever tried a 2500 or so launch?

Anywhere between 3500 and 4500 with a converter that would "flash" to between 6700-7000 depending on air.

Car would always 60' about the same whether it was 3500 or 4500. Just a lot more violent the higher you leave on the chip.
