Right now I am 26 years old and have been playing my stepdad's dci 762 for 10 years now. I dont know much about these irons at all. Are they considered blades? or Cavity backs? What I do know is I need to upgrade. Money is an issue for me but also I want to play the best golf. Which irons would be best for someone who has a lot of strength and swing speed? Are the 716 really that much better than the 714? Here we go! The money question! Should i go with the AP2 or the cavity back? 714 or 716? PLEASE HELP!
