Compare shafts and get the answer first: what is actually different, computed from the published figures — even across brands that describe stiffness differently.

Pick one shaft and the tool offers its natural rivals — same slot in the bag, nearest published weight — so the second pick is one click. The comparison opens with what differs, then the full table: weight, torque, tip, and every spec each brand publishes, plus a normalized cross-brand stiffness profile so a Fujikura, a Mitsubishi, and a Graphite Design shaft line up honestly. Toggle “differences only” to cut the noise.
