975D was the sweetest driver ever made. took me years to get away from it. I've hit tons of drivers since then and have stuck with the TM 510TP from about 6 or 7 years ago. Can't find anything I like better today. It sets up dead square (like my 975 did) and hits a high boring shot. I probably could find something that lowers spin, but it'll have a hard time making the bag.
Still hit MacGregor blade irons, down to the 3. Am looking at going to the x-tour from Callaway since I think they've worked out the hooking issues it had.
I have changed putters a bit, but I still always go back to a Cameron studio blade, which I just replaced with a Mizuno Bettinardi blade and may never change again.
I do change out my 60 degree wedge about every 18 months.
