I golfed alot last summer and i plan on golfing alot in the year to come. I was using a set of old clubs i got from a friend. I am about a 20 handicap so I have been looking game improvement irons. I have in mind the Ping G10 xgs, the Ping G15s, and the TM 2.0s. I have hit all three and am leaning towards the Pings. As a new golfer would I benifit from geting the G15s vs the G10 xgs for the 100 dollar diffrence?
