I have a UST Recoil F2 ES 440 Light shaft in my driver. I am thinking of getting a new 3W and getting a similar shaft as in my driver but just a little heavier in weight, e.g., UST Recoil F2 ES 450 light. Does this shaft seem like a logical choice to try ? My driver swing speed is only 80 mph. Also any other shafts that have similar characteristics as the F2 ES 450 Light that I might try. Thanks in advance.
