YankeeJim: The most obvious difference was missing to aim the putt.
I agree 100%. I ALWAYS putt to miss the ding. It just seemed like the way to do it when I first started, and I've grown accustomed to this. When I bought the Ghost (should have rented it first) I found that there was absolutely no "feel" on this club when you missed ding. It was very accurate when dinging, but did I really want to learn a whole new way to putt after all this time?
Suffice it to say, I played only a few rounds with the Ghost before selling the thing back, at a nice little profit for WGT. My advice, if you are a ding putter, go for it. If you putt to miss ding, don't go anywhere near the Ghost.
