I've been experiencing the same problem. Had to withdraw from a CC tourney because of the inconsistent club distance.
ex1: Had a 8MPH tailwind at BPB #2 , pin was playing at 165 yds, I'm in the fairway and dinged it at 160 yds.....result: ball traveled 134 yds and short of the green.
ex2: Same thing at Kiawah #1 yesterday. Headwind 5 MPH, 134 yds out, dinged it at 136 yds with a result of only 120 yds.
There's been a lot more. Even the new Celtic Manor CTTH is off. First 4 holes my shots came up 20 to 30 yds short.
What's up, WGT?
