I am a new player that was looking for game improving clubs so I ordered a set of TM Rocketbladez. I made the mistake of getting the clubs in stiff flex and my swing speed is just not fast enough for them. They feel very stiff and I don't get the feel of the club head that I want. My question is: where is a good place to buy replacement shafts? I want the stock TM shafts in regular flex. Thanks guys for any info.
