I also took about a decade break from golf...
Upon my return, the differences in the golf ball was by and far the most significant advancement. I was a 3.8 handicap using Balatas and the Professional 100. There isn't much in common with today's golf balls and the ones made 10 to 20 years ago although you could probably match putter feel to the professional 90.
I would suggest buying any ball labeled "soft", like the Nike. I currently use the Titleist Pro 1Vx and am amazed by its performance, although I hear it is just like some other cheaper ball callaway makes?
