I flew the 412 in ATT mode all the time. If you need to change the attitude, just press the FTR briefly. You don't want ATT mode engaged on the ground, since you can get interesting results, but I kept it on from just before liftoff until at flat pitch after landing. In the S76, I just moved the cyclic as necessary, without worrying about pressing any buttons. That's one reason the S76 is more fun to fly, you don't have to worry about tiring your thumb out. I've never met a single pilot who would get in a 412 if (s)he had a choice of an S76.
