Thanks for the response, folks! I'm definitely leaning towards a slightly older model (which will be cheaper) so I can afford to have it properly fitted. I don't think, with my game, that the latest and greatest will show marked improvement on last year's latest and greatest, and getting something fitted will probably have a much larger impact than getting something slightly newer.
Outside of flex and loft, is it likely that shaft length will need to be tweaked? If so, does a place like golfsmith do that?
