Anybody use a low temp temper with 3-v and have good results?

i do and love it
have to use cryo tho, the high temper range is to get rid of RA
if you dont use cryo you will not get rid of the RA at low temp tempering

Is cryo nesassary to remove RA from 3v or would -108* dry ice/acetone bath still be ok? Im guessing it would..
