...it doesn't make a single bit of difference.
Perhaps not to you. For me, PG works well in the duck blind when there's usually time to prepare for a shot and I'm wearing warm gloves. But it
does make a difference for me in the grouse woods. For quick, instinctive shooting the PG seems to get in the way a bit, and I feel that a SG mounts quicker. But, as you say, whatever works for you.

For skeet, I always shoot low-gun with the safety on when I call for a pull. The point is to make the whole mount-and-shoot action instinctive, so that the only thought is the bird itself.
