Hey,
I would suggest seeing one of my fellow Titleist fitters to compare. There is no stock graphite shaft as there is an upcharge for them. If anything stick and your going to spend the money stick with recoil as T300 are the least expensive head we have so your overall cost shouldn’t be bad at all.

When you go see a Titleist fitter, they will fix you up with a shaft that best fits your new numbers. Go with an open mind, it may be another shaft. Leaving this answer up to the fitter. With respect. =)

Well, if you go with T300 and do a fitting, you might find something that matches your shaft needs even better than the Recoil. There is no up-charge for some of the shafts so no reason not to at least try and get fit as opposed to of-the-shelf offerings. Most T300 store models will have Tensei Red or Tensei Blue graphite shafts. Red having a lower kick point for added height and usually offered in regular flex. AeroTech SteelFiber has become a very popular option, especially for those looking for the weight and flight characteristics they had in steel. Those will have a up-charge added.

None. Every shaft has it's own characteristics. The Recoil 95 is available so if it works for you it's worth the extra cost.

It is best to try it out from your fitter. To me shaft is really personal feel, it is hard to say which is similar or suits you best.
