What to expect from a woods fitting?

[Shindig]

Executive summary:  what should I look for in a woods fitting?  I am aware of the rules in LSW about this, but I know almost nothing beyond that.

Full story:  I have never been fitted for woods, other than my driver and possibly a hybrid suggestion when I got my irons.  When I started golf, I eventually picked up Cobra F-Speed woods (regular flex), 3 and 5, and Cobra baffler hybrids.  I had a thing for Cobra clubs for a while.  At some point, I thought (correct or otherwise) that I'd hit a 4-wood better than a 3 or 5, and got a Nike SQ^2 4-wood, also regular flex.  I also got Nike SQ 3 and 4 hybrids at some point.  For both the Cobra and Nike woods, I was guessing on just about everything (and I bought used, or at least off the shelf, in all cases).

I later got 3 and 5 woods, plus 3 and 4 hybrids, in Maltby, with stiff shafts.  Again, I was guessing the right shafts and such to use.

Lately, I have been carrying the Nike wood and hybrids with me, although with my current (fitted) set of irons, the 4H is higher loft than my 5-iron, and gets about the same expected distance, so I won't be carrying both for a while (I plan to keep the 5-iron and replace the slot the 4H occupies).  I switched back to the Nike woods when I got my irons last summer, as they are regular flex (replacing a I-guessed-stiff-flex-when-buying set of irons from six years prior).  

In any case, I now have Game Golf data;  using my eight regulation rounds this season, I'm expecting 222 yards with the driver, an average that includes plenty of bad drives (15 drives have provided me less than 190 yards, some due to trees) but only 184 with the 4-wood, although five strikes with that club have provided me at least 200 yards each (there have also been several... poor strikes). The 3H is getting 175 yards.  I play my 5-iron to 160-165 yards.  I also hit punch and trouble shots with it.

I have been debating replacing the top of the bag (except driver) for quite some time.  I'm trying to figure out what I should look for in terms of a fitting.  I'm not sure I've ever gone for a full hybrid/woods fitting, although I think the Ping rep who fitted me for my irons suggested what I should get for a 4H if I were going to make that purchase when I got my irons.  I don't imagine my specs have changed that much since then, so that's probably fine for purchasing if I so choose. 

Ideally, I'd like some club that I hit as a strong second-shot on par-5s, plus fitting some gaps down to the 5-iron.  

Lastly, is this (a good suggestion for clubs and their specs to fill these gaps) something I can get from a OEM demo/fitting day, or do I need to go for something deeper?

My bottom line expectations from a proper club fitting are better, more controlled ball flights, which equates to lower scores.  To me that's all a golfer should expect.

You should expect to hit woods 

@Shindig, I think you're kind of overthinking it. It's pretty similar to an iron fitting. You go in with your current clubs, tell the fitter some information about your shot zones and your common misses, then you hit different clubhead and shaft combinations.

And no, if you want a comprehensive fitting, you probably won't get it at a demo day.

Thanks you two.  I appreciate it.
