Re: 20 handicappers hitting 300 yards (mild rant)
Well, I am (or was) about a 20 or so (just returning to the game and have not played a round in years). My SS was right around 95 give or take a little, and my good drives, on those rare occasions when I hit a good one, were about 230 or so. I do recall on one particularly hot and dreadful day during the middle of a drought, hitting one of my good drives that landed at the point where the fairway slopes downward, getting a hard bounce off the concrete-like hardpan, and ending within a chip shot of a 350 yard green. So, yeah, I guess I drive the ball 340 too

Seriously, that was one drive where course conditions allowed for something well outside my norm.
I also do not hit 9 irons 150, but when I was playing well, 150 was my 8 iron distance.
