Which aircraft? What configuration? IMO it makes a difference.
In the B412 & S76, I use the hat, or the interrupt button. Flying the 412 especially, against the AFCS, is counterproductive, at least in ATT mode. That will get you into all sorts of trouble, ESPECIALLY if you get vertigo. You completely confuse the AFCS, & if both of you are confused you're in a heap of trouble. Bell says it has to be in ATT for IFR, & every night takeoff in my aircraft is in ATT, because it's IMC as soon as you clear the platform helipad, or the ship. I simply consider night as IMC all the time.
OTOH, if you're in something without AFCS, then the CAF technique might work, but I still prefer to keep the aircraft trimmed all the time, whatever the attitude. If you have vertigo, a little pressure from the cyclic is not going to put you straight & level, no way, nohow.
