I think custom fitting can make a real difference if you goto a decent club fitter.  If you goto a sales person who works in a golf shop then its not worth much!

Maybe you could look at going to a club maker and have them make you a driver that will suit you, it may not be a named brand but should work better than an off the shelf fashion accessory.

Agreed, a fitting with a club fitter can take a couple of hours and may even end up with adjustments to kit you have as opposed to buying something new. I found it well worth it as I ended up with a driver that  I could actually use.

If done properly - a boon

 If not - a waste of time or worse

Do you think I would get custom fit and suddenly add 30 yards to my drives? 

Absolutely not.

 Might add 5 or 10 yards length and maybe 20% better dispersion/accuracy.

Yeah, it probably should be a little higher.   According to my stats proggie I'm missing 25% right and 15% left, so could be anywhere really.  Only 40 odd % GIR too, so my long game is suffering really.  Good job my short game is just holding together (for now).  Do you think my stats should be better for my handicap?  Average up and down is 35% and average points are 38 so I'm still playing slightly under my handicap (going slightly off topic here sorry).
