Question about fitting.

First post here, happy to find this board.

Briefly, I'm an old guy (63), kind of heavy (168), really a novice golfer but I practice on the range an awful lot. I've been taking some lessons and I go out on Executive Courses to practice hitting off grass. I can get around but I'm really still learning to hit my irons a decent distance (hitting fat means my 7 iron goes only about 120-130 yds, although I can hit it straight).

My question (this one, anyway) is simple. I know I could ask my instructor, which I will, but also thought feedback here would help. When I first started golf a few years ago I bought (through the lesson plan) a set of Wilson Ultras, I guess real cheap clubs with steel shafts. After taking a few additional private lessons my instructor at the time suggested I try senior/lighter clubs. He wasn't selling them but did let me try a Cobra (I think it was an S3). Very light and I hit the ball better, it really felt good. So I went out and bought a set of MacGregor MT OS irons/hybrids with graphite shafts in Amateur, or Senior, flex (A). While they weren't the Cobras I thought the answer was the graphite shafts and they were considerably cheaper. This purchase was from Golfsmith but I believe the set was made before they took over the entire MG line. Nice clubs, etc. I know it's been a long time since I started, but my question is this: I'm short, 5' 3" on a good day, and I wonder if I would benefit from taking the clubs to a fitter and letting them check them out, perhaps replacing or resizing the shafts. I know it seems I'm looking for an excuse for my relatively poor performance, maybe I am, but it's possible it might be a good idea.

Any feedback would be appreciated.

I'm an old guy too, 62.  When I read your were heavy 168, I thought jeeze I must really be heavy at 235.  Then I see I am 9 inches taller.  At any rate, you can always benefit from getting fitted, I suspect at 5'3" you could certainly do with having shorter shafts.
