Skip....it's funny that the pros that do switch brand clubs never seem to play as well afterwards and some do not win again for awhile. I can't come up with any pro golfer that switched brand clubs during the off season and even though they have their golf clubs custom tweaked, all of the pros seem to struggle for awhile. The TV golf announcers always make it a point of discussing equipment and swing changes and point out how the player hasn't quite mastered the change quite yet, It's never the wedges or short irons but the mid-long irons and woods & driver changes can become extremely vexing. Eventually the changeover gets worked out and as I previously alluded to, endorsements make up for a while bunch of tournament winnings.
