I have read many threads asking which heads, shafts, balls etc. other TT members "think" they should purchase.  Although I'm also guilty of sitting at home wanting to talk golf and options, It's not even close to being the correct way to choose your products.  Fittings can be expensive but when your spending your hard earned money and looking to improve your game there's not really any other option.  Take the time to get the hard numbers from a trusted fitter, and not from online buddies.  For anyone who hasn't been fit by a Titleist Fitting Center, I assure you it's worth the investment and you will enjoy the experience.  If a Titleist Fitting center isn't an option, then take the time to see a club pro or at least  a retail fitter.  

Hope this helps, and have a great 2013 season!
