I've been absolutely floored with the 915 series. I've always been a Titleist driver and fairway wood guy aside from the couple of years that I played a TM Driver (R5 TP with a Diamana Blue Board 83 then an R7 Superquad TP with a Rombax 7W06), though I've never played anything but a Titleist fairway wood since the 975 series. The 909 driver was great in its day, and with a White Board 83, good enough to kick my Superquad out of the bag. The 910D2 with the Kai'li 70 was another huge leap forward, but the 910 Fd with the PX 8A4 was something spectacular that's been in since the release of the 910 series for me. I tried a 913D2 for the last couple of years and didn't see a drastic improvement in performance over my 910, but maybe its because the 910 was just dialed in right for me. The 915 series, though, it's something special. I've gotten the driver, Fd and hybrid. I went with a 915D2 with the Kai'li 70X, but right now I'm testing it with an S+ 70 TX at the recommendation of my club pro, I've got a 915Fd with an S+ 80 and a 915H with an S+ 90 and I have another hybrid with the same shaft incoming. The driver has added about 12 or so yards to my driving distance, not an enormous gain, but nothing to sneeze at. The very impressive thing with the driver though is that a slight mishit is not penalized on distance or direction the way that it was with the 910 and 913. The really special clubs are the fairway and the hybrid in my opinion. I'm getting a good 20 more yards more out of the respective 915's than I was from my former 910Fd and Adams hybrid. If you're on the fence, demo the 915 and if you like it, go for a good fitting and don't look back.

I bought the 915D3 9.5 degree and have it set to no bias. It has a 70 gram Adila shaft, hits great and very forgiving. I would recommend it to anyone.

I recently switched over to titleist. I was playing with the R11s and now I have a 915 d2 /9.5 degrees.  My drives are much longer and straighter than with the TM driver. So happy I made the switch. Hope this helps

Congrats, Dennis.  Wise decision.  

Matt I played png until the end of last year when I switched over to Titleist irons (AP1 714), the feel is amazing and after that got the 915 woods, and just last week added a 54 and 58* Vokey SM5 wedges to the bag (Titleist mid size staff bag) and could not be happier! My next thing is a Scotty putter somewhere down the line this year. Titleist is #1 in quality and customer service as far as I am concerned, I am a Titleist guy for good. I'm hooked! You can't go wrong with it.
