Modern Shafts

For those of you playing modern gear.

Does anyone have any experience with the Aerotech steel fiber shafts?

Im thinking of putting a set in my wedge through driver.

They make an XX driver shaft which Im thinking of putting in my driver to take left out of play.

Would really appreciate people thoughts and opinions.

Dont worry i still have a proper set. Dynapowers and a newly refinished M85 macgregor 2 wood.
