This was from another thread, but figured I'd post it here.
I was playing a 910D3 8.5 in C1 setting with a GD-DI 6 shaft since it came out.
I was going to automatically get a 913D3 8.5 head as it is the logical progression.
My fitter and I were trying different combinations, and the D2 still produced ideal launch conditions for me, so I figured why not.
The 913D2 shape is much better than the 910D2, with the top line looking more square edged like the D3, for a lack of a better discriptor.
It is definitely more forgiving than either D3 head, both me and my fitter, who is a +1, who both used 910D3 in 8.5 and 9.5 have switched to the D2 8.5 head with our old GD DI 6 and Kiyoshi shafts.
The spin properties or so called draw bias of the heads are not nearly as drastic as people on here would lead you to believe. Hit the D2, you might be surprised. Does the D2 turn over a little easier than a cranked open RBZ Tour head? Of course, but a D3 head? very little difference. Similar LA and Spin numbers with my old 910D3 head, but maybe a couple extra mph in Ballspeed and definitely more forgiveness for the 913D2. With the D3, I used to tee it up with 2/3 of the ball above the top line and have a strong AOA, but now with the D2, I tee it much lower, go at the ball with a far less aggressive AOA but still get the same launch and spin properties. Granted is it all the club that has made that change? No, it was partly the indian, so to speak, but the shape and performance properties of the club is what made those changes possible.
With so many low spin shaft and variable configurations for shafts, I've been telling my friends to get the D2 head for its full 460 size, and then fit the shaft to adjust launch properties.
I'm loving my 913D2 setup. In the last two months I've been playing the RBZ Tour 9 degree head and absolutely love hitting bombs with it, but the 913D2, while it may be a little bit shorter in total yardage (admirable considering the shaft length difference with RBZ) is much more consistant.
Enjoy the hunt.
