I am using titleist dci 981 irons witch i purchased in 2000 (ca). I haven't played much golf in recent years and my swing is more restricted as not so supple as before. I find it difficult to hit sound iron shots (especially 3-5 iron), also i have lost distance especially with these irons. I'm "back to business" as far as playing golf at a regular basis is concerned (54 holes a week). Hoping to cut my hcp. back to were it was (4), what titleist irons should i buy? Any ideas?
