Stretch,  I am certain that Titleist will work with you in any way they can. but please first try the other things I mentioned - let me know how it is going.

I would say 6'8" isn'y that far off from what stated about 2* upright and 2" long. 2" long adds about 10 swingweight points. If you used standard length, you would be 4* upright (Ping Maroon). +1 would be 3* upright. Ping Eye green dot is 2.25* upright. Before I sent my irons to Ping (most fitters will send them back), I was choking down about 1/2-3/4"; otherwise I would take some turf and hook it. I had them flattened to yellow dot. "over the top" is actually caused by swinging too hard (this is a golf tip from Paul Wilson of Revolution Golf). The arms take over and that is what causes "over the top" (but when most do that, it is a slice). 200 yards for a 6 iron is pro range.

Although I personally may be an amateur, I got into clubmaking as a hobby and constructed a set of irons, a couple fairway woods, a couple approach hybrids and a lob wedge. During this, I learned the importance of proper fitting, effect of shaft and grip changes on swingweight and also what fits my swing (had some assistance with a local clubfitter along the way). I know that 2" of additional length = 10 swingweight points for a steel shaft. a 43 gram grip increases the swingweight 2 points vs a standard rubber grip. The tip from Paul Wilson on swinging easy WORKS. The reason people slice or hook is they hit it too hard! What would be the point of being able to hit an 8 iron 160 yards if you end up in the bushes? I would rather hit it 135 and end up on the green every time (and that is exactly what I do). As far as distance, I drive 230-240, hit a 7 wood 180-200, a 5H 170, 155 with a 6 iron and so on but pretty much dead straight. I obviously have the same distance as the average "hacker" on the golf course but score better (mid 80s on a par 72 course and near par on an exec) because I have a strong short game and I hit the ball pretty consistent. I just had my Ping Eye 2 irons reshafted to TT Lite XL regular and they hit much better (I also have a set of DCI 981 irons set 1/2 deg upright that hit well but the Pings are easier to hit). I see breaking 80 soon since I'm now zeroed in.

stretch -- any updates ?
