The Titleist Diamana Kali will launch higher and spin more than the Project X.

A shaft to consider rather than the Kali would be the Diamana S+ in 72 gram version.

Should be easier to properly load the S+ more than the project X, as the project X shafts are in between flexes, more towards the higher side. So a Project X 7C3 plays similar to a stiff plus flex.

Look at the Titleist charts for shafts on the website, pretty accurate for launch and spin characteristics of shafts offered.

Thanks Robert, as a matter of interest would the  Diamana Athina s flex be more of a match, as i have the chance of one at a good price.

thanks

The Ahina will launch lower than the Project X, and feel firmer overall.
