I've been keeping an eye on this thread and registered to add my two cents.
From the very end of last season to the start and middle of this summer, my swing just fell apart. No distance, no control, no anything. Pretty bad. Like going for 40-45 for nine to 60-70.
I've been trying to move to an in-to-out swing because my down-the-line swing was straight, but I was getting almost nothing as far as distance. Since moving to an in-to-out swing my distance has jumped back up and my accuracy hasn't changed much for the worse.
Golf is just like baseball (my other favorite sport to play). Whatever works, works. But so far the in-to-out works for me.
