I like the 910F so I would assume the 913F is no different.  What I like is the adjustability.  I played TM for a year and a half so I started out with the most upright lie angle (with a draw face) on the 910F and now I am back to the standard lie angle (with .5* open face) and hitting it much better.

I've played 975F, 980F and now play 910F.  The 910F is more forgiving than the 975F.  I have a Bassara A flex shaft on the 910F and it has a lower ball flight vs the 980F with stock regular shaft.  I also love my 910Hs to death (21 with Bassara A and 27 with Bassara R).

Jacob-

The 913 fairways and hybrids will not be in golf shops until February, if that influences your decision.  We think you'll find that they're worth the wait, however.  Let us know if you need help finding a fitting location near you.

Brice, Will they be fully adjustable with a sole weight too? 

Josh-

Yes, the 913 fairways and hybrids will still feature the SureFit Tour adjustable hosel and interchangeable sole weights.  Full product information is available on Titleist.com as follows:

If you are in Ohio, depending on where in the state you might want to go to Miles of Golf near Ann Arbor, MI.  They are a Titleist regional center with Trackman fitting and every exotic shaft to try.  And the nice thing is you are hitting from inside the building into the driving range so it is completely comfortable in cold weather.  It is very impressive.  

I have a old 906F2 fairway wood and thing of replacing it with the new 913 series. What would be the replacement in the 913 series the 913F or the 913FD ?

913Fd would be closer, but the F2 is in between the F and the Fd. The 906 head is closer in size to the F, but the F will probably go and little higher for you.
