Titleist AP-3 Swingweight Question in Boom Sticks Posted 9 hours ago 2 hours ago, sager said: Hello forum members. I wonder if you can help me with an iron issue. I got a new set of AP-3 irons two years ago and (believe it or not) just realized the swingweight feels way too light - no head feel compared to a couple of friends' irons - Mizuno EZ/graphite and Srixon 565/steel. I know it's not precise, but using an online tool and carefully weighing and measuring my irons I came up with a consistent swingweight of C8 for them; the Titleist website indicates they should be D2 (not specified iron or graphite). My shafts are Mitsubishi Tensei CK red. I know some other iron manufacturers state a one-number lower swingweight for graphite versus iron shafts in their clubs. My question is what should I do in terms of changing the grips (currently GolfPride Tour Velvet 360 Midsize, 53.5 grams) to get my irons to a swingweight of D1 at least? One option I have read is change to lighter grips - have heard that each 4-5 gm lighter grip changes the swingweight one point. I plan to change to standard size grips with one or two wraps of tape. Your suggestions are appreciated. You are correct grip would be about 5 grams per swingweight point. You want to move 3 so that would be about 15 gram so you would need grips in the upper 30 gram range. Winn Lite grips would get you there. You can also increase weight at the head of the club. Easiest is lead tape but you could also add tip weights if you wanted to disassemble the clubs.
