I have felt the same way until recently. A buddy and I have been sneaking on for 9 holes several times in recent weeks. I figured I wouldn't even keep score just get high and have fun. To my chagrin I played well for the most part. We played a full 18 and I got high before and shoot and had decent front and got tired on back and sucked. Next time I played 18 I got high several times after 9 and played my handicap. My short game is a little worse and my long game is better high...
I'll bet it slows your swing down a bit and that is usually helpful for the long game!my long game is better high...
