Feedback is a fundamental part of the learning mechanism. It is also a fundamental part of practice. The total absence of feedback renders learning impossible. More is better, less is worse. In order to increase one's own ability, one must learn further and practice further. Learning, practicing and increasing one's own ability does not exist without feedback.

Feedback can be described as the information one acquires directly through the act of doing. The information is primarily physical sensation. Without this information, one can not learn from one's own deeds. My action, from my hands to the club, feeds back to me, from the club to my hands, my success or my failure. A blade performs this action better than a cavity back. I play better because of that.

Cavity backs feel numb, or unresponsive if you prefer, to me. So do graphite and supple shafts.
