I most be honest im a total noob on shafts.
Is there any site, or link, here even which gives good account of different shafts, and what they do and who they might help me?
The Titleist custom options booklet offers what you may be looking for:
Starts around page 4 and continues for a few pages.
These charts will give you a starting point but I suggest testing them out on a launch monitor before making a purchase.
