How this shaft reads against the database
Flex
Weight and torque against every iron shaft
Every iron shaft variant on record publishing both a weight and a torque, binned by density — the ringed marks are this shaft.
Launch and spin, as published
Aerotech rates this shaft high launch and high spin — the shading is how many of the 486 rated shafts on record share each square.
STIFFNESS BY SECTION
Neither Aerotech nor our derived profile has a stiffness reading for the butt, mid and tip of this shaft. Nothing here is estimated, so there is nothing to draw.

- Aerotech's own specs, partly built.Taken from Aerotech's product page. We haven't found their full spec sheet for this shaft yet, so some figures they publish may be missing.
- Flex options, built.2 flexes, each with a published weight.
- Launch, spin and torque, built.Published for every flex — the figures a fitter compares shafts on.
The site is in beta and the database is still being built, so expect gaps. Know something we don't? Help us fill it in — a link to where it's published is worth more than anything else you could send.
