Karlsson Adjusts to Grooves Rule with New Set Comp

Titleist Brand Ambassador Robert Karlsson continues his return to form, having recently won the Commercialbank Qatar Masters on the European Tour. After a successful 2008 season during which Robert captured the European Tour Order of Merit and rose to number six in the Official World Golf Rankings, the lanky Swede missed four months during the heart of the 2009 season due to an eye injury. With the win and several other strong results since returning to competition late last year, Robert is back inside the top 20 of the OWGR. Always looking to improve, he worked with the team from the Titleist Tour Van during the WGC-Accenture Match Play Championship on an adjustment to his set composition resulting from the new groove regulations.

Titleist Brand Ambassador Robert Karlsson looks on as Chris Tuten from the Titleist Leadership Team checks Robert's irons on the loft and lie machine.

Practicing and playing with the new 2010 conforming grooves in his wedges over several months, Robert has found that his Vokey Design Spin Milled C-C 60° produces a higher trajectory and shorter carry distance than did his previous Vokey 60° wedge. With four wedges in his bag as well as a long game yardage gap between his 18° 909F3 and MB 4-iron, Robert and the team decided it was time to fit him into a set composition with tighter yardage gaps while allowing for the requisite short game versatility.

Robert had been playing his MB irons with 1° strong lofts (6-iron at 30°). To bridge the gap between his 18° fairway and 4-iron, the team built him an MB 3-iron at standard 21° loft and adjusted his 4-iron back to standard at 24°. The remainder of Robert's irons were adjusted to 1° weak, with his pitching wedge at 48°.

Next, the team built Robert several sets of wedges to help him determine the correct models, lofts and bounce angles to meet his short game needs. Robert worked with all of the wedges in the short game practice area, hitting the various shots he needs for his game, and determined that a 53° and 58° set-up was ideal. Robert previously carried 49°, 55° and 60° wedges in addition to his strong pitching wedge.

    Bruce - The Pro V1 and Pro V1x golf balls are an appropriate choice for any golfer looking to shoot lower scores.  Both balls provide long distance off the tee for a variety of swing speeds as well as exceptional playability around the greens for improved scoring performance. To find out more about which Titleist golf ball is the best fit for your game, be sure to check out www.titleist.com/ballfitting.

    There is no question that the Pro V1 & Pro V1x are great golf balls but your forgetting the ladies and seniors. You should come out with the Pro V1-L and the Pro V1-S for the ladies and seniors. I am sure the Pro V1 name alone will sell more balls to this market.

    I totally wish I had access to the van. Man, that would be sweet.

    When bending a club for loft, bounce angle is affected proportionally. For example, bending a 52° wedge 1° strong to 51° will decrease the bounce angle by 1°. In terms of loft gaps for irons, there is no right or no wrong.  Players must choose the 14 clubs they feel give them the best opportunity to score their lowest.

    Can you please explain what effect bending a 52 wedge to 53 or 51 would have on the bounce?  Also why do irons have a 4 degree gap between each club?  Is 5 degrees too much of a gap?
