I played a full round of golf today and lost my ball on the last fairway drive on the 18th hole in the water. Off the tee, I'm losing about 30 yards, but on the fairway, I'm gaining almost 50 yards. I golf at least once a week, and I haven't made any changes in my swing mechanics, so I'm really confused. There is no difference in feel on the green. I normally play Precept Lady IQ 180 Clear. The only difference between the two, the Precept tends to cut easily--the Diva still looked new off the 18th tee.
