Fellow lefties,

I recently purchased a new set of Mizuno MP-57 and it comes with the standard True Temper S300 (approx 125 grams) stiff shaft - I used to play Taylormade RAC with the T-step (90 grams) stiff shaft. I enjoy the lighter shaft for greater club-head speed. My question... can I swap shafts from my RAC Iron set with my MP-57?

Many thanks for your feedback!
