I bought a new set of TM LCG back in 98 with S90 shafts. I really like the way they feel compared to the shafts on my new Speedblades. I cross referenced the s90 rifle and there like the Project x 5.5 rifle which are big bucks more then what already I spent on the Speedblades. My old shafts still look to be in great shape, so I wondering if I can just swap them out, especially since my old irons are not worth much.
