The most important aspect to a golf club is the shaft. The best answer here is to get fitted for a shaft. I have a swing speed of 125 and the titleist tour van fitted me for a shaft and I have never hit a driver so well with so much control ever. It made a HUGE difference. I would go to a golf superstore and USE THEM for their technology as many club pros do not have the technology needed. (swing speed, etc.)

YS-6 is a stiff flex for a slower swing speed such as yours.

If you hit your hybrids fine, I wouldn't change anything. They make special hybrid shafts for those types of clubs so make sure you buy the correct equipment. Hope this info helps!

thanks for the info... i did actually get fitted for the Hybrids and do really like the results i get from those... i am looking to get into the new 910 like everyone but was just curious based on the swing speed and the prior results i had from using an S flex. 

I second his coments about getting fit for the shaft. i am an avid promotoer of this. and like he was saying the shaft is the most important part. As technology is evolving there learning that the shaft is more important than the face angle. So deffinetly deffinetly get fit for the shaft. Its more than just a simple r,s,or x rateing there are kick points and shaft weights that mater alot. i have had a guy try to fit me in a 85 gram s flex with a high kick poin low torque shaft  but 90 percent of fitters stick me in a 73ish gram x flex with high kick and low torque. for me its all about getting my launch angle down with low spin. so if you were swinging a heave regular and were getting better results than a light stiff it makes sense the whip may have been puting alot of spin on the ball.  get a trusted fitter to put you on a lauch machine and deffinetly get fit for this club. good luck with this process look forward to hearing about your results

Question for the mods.  When will the Titleist website be updated with the new 910 line along with the available shafts in the custom/upgrade section of the website?  Thanks

I agree with the others response.  Fitting the clubs are essential.  But also got to figure out what flight (launch angel) you are looking for and if you are looking to move the ball (left or right.).

I got a fairly fast swing with the driver I am around 105 - 110.  I am huge fan of smaller drivers, so I am still using my Titleist 983K driver and I have been lucky to be able to buy to drivers - one with a stiffer regular shaft - which a 10.5 degrees - and a one with a stiff shaft - which is 9.5 degrees.  I actually changed from an 8.5 to a 9.5 a couple years as I couldn't enough club head speed on 8.5 to get the launch I wanted. The drivers both give me quite different flights that I need on my course.  Depending on the wind I want keep the ball low or less wind I just want to bomb it down the fairway.  I most at least have tried 30 shafts and some one of the once I use now I would never expected to work that well. 

Its amazing though when you find the right shaft - using the driver is just pure enjoyment.

Have fun and good luck

I agree with getting fitted for a shaft. I have played a 983K since 2003. I was in a Golfsmith and picked the club up just to hit a few balls. I had to take it home. I have tried a few other drivers since but always end up selling them on Ebay after a few weeks. No other driver is as consistent as my 983K. A couple of year ago a friend wanted to hit it. He hit the ground and snapped the shaft. I took it to Edwin Watts. The fitter said they could give me a similar shaft but the only way to get the same shaft was to send the driver to Titelist. I wanted my club back so away it went. The clubs were selling on Ebay for less than I paid for the shaft but I could not be sure they had My shaft. It was money well spent. The club came back as good as new. I recently purchased an R11. I have tried it for three weeks. You can pick it up on Ebay this weekend. The 983K is back in my bag.
