No it isn't; Helping a pilot new to a type is a valuable process.

Not quite sure why some are putting them down, Most of us like to try to help here.

I just grip it very lightly with my fingers on the "finger rest". No finger rests on the PTT switches or on the trim switches. I just deliberately put them there when I need it.
Maybe this is not text book correct, but I drive my car the same way, just barely holding the wheel with enough force/grip to make the movement I need. I know that If I face anything challenging natural stress will make me grip harder without me even noticing :D

Try to find a way to handle the control column without that, as you might have to fly a 737 in the future that has a different type of rocker switch on the control column - some of them latch in the I/C position, others don't, just like on the ACP.

New to the 737 and I don't like it either. No matter how relaxed you hold it, you still have to be careful to avoid the PTT. I've been experimenting with various grip positions that are all uncomfortable and defeat the point of the contoured grip that's clearly designed and intended to be held the one way...
