Hi I am a senior who just graduated and am looking for a new set of irons. I really like the 712 cb's but I do not know what shaft to put in them. I was thinking of the dg x100 tour issue. Right now I am playing 710 ap2's with px 6.0 and they are launching into space which makes them hard to play in these North Dakota winds! I am looking for these irons to help me walk onto to the college golf team which I am attending.
