I am looking to purchase the straightest game improvement irons in the market (8, 9, P, AW). I dont care about looks, feel or working the ball. I currently play the Rocketbladez Regular flex and they are fine, but I want to see if there is something even straighter, higher and longer out there. I am currently thinking of trying the Altitudes, new big berthas and TM Rsi1 irons. Does anyone have any other suggestions.
