I agree with you...
I play to just over a 9 handicap my backswing has no wrist cock (of significance). There isn't much of a forearm roll. Just a smooth swing back and a smooth swing through the ball.
My hands never get any higher than chest height. I swing a "Y" back and a "Y" through the ball...
Trail hand's trigger finger (index) gives a little steady pressure on the forward swing.
My grip is unusual (single axis and the butt of the grip grip is in the center of the lead palm).
A 43" inch Nike driver, 13* sends the ball about 200 yards. High and straight. At 62 it is fun to enjoy golf. At 46 I was on the Merry-go-round trying to hit the 275 yard drive. Read five dozen books, a thousand posts... watched twenty DVD's, took lessons. Some positives, but rare and none lasted.
Not flexible, still strong and fit, but slow moving (with the limited range of motion). The underhanded, "Half Swing" I employ allows me to beat the crap out of most of the folks I play with.
My Y to Y swing doesn't change for the short shots; just lower the amplitude and make the same motion.
Do what you can do and have fun. Instead of attempting to do what you cannot do (and have very little fun).
