I cant answer all your questions, But yes you can definitely bend the Titleist back to standard. The usuall cost to bend irons is about $5-$7 per iron. As far as how much bending not sure but if RForged said 6* he is probably right. As far as weakening the iron you would probably have to do alot of bending back and fourth....... Forged irons are just awesome, I am so happy I bought my new set of Nike forged they feel so much better than my old set.. They rock...
