The TC-201 offers the performance of a muscle back with the increased forgiveness of a cavity back. The progressive weighting in the sole provides a lower center of gravity in the long irons for added height and higher trajectory on longer shots. Slightly changing to a higher center of gravity in the short irons creates a lower trajectory and more control on shorter shots. Constant weight towards the heel and toe helps with off-center shots. The sole design contributes significantly to the playability and forgiveness of this club.
