For me, I don't do "straight arms" at address. Plus, watch the pro's on shorter irons. Their hands are very close to their zipper. IMO, never get too far away from the ball because that incites a flatter shoulder backswing. More vertical than flat works for me, but I could be weird...I've been told I'm weird...so maybe I'm wrong? LOL.
@GolfLivesMatter - We are all "weird" in our unique individual nuances, even the best players in the world. Ball striking and shot shape tell us everything we need to know!
