Has anyone tried this driver? Looking for some feedback and interested to see what the major differences (other than head size) with last years Legacy Driver.

It's more the head shape and design than just the size and changing the shape and design make it a different driver all together. They share the hyperbolic face idea it is a new face with different titanium (ELF) and smaller but longer "X" (starting to look like Yamaha's X inface). This face is supposed to slightly change the feel and sound as well as produce less spin. Instead of using the power weighting that the Legacy does there is a convex shaped heel with 24g of weight to help square the ball and increase MOI. It of course has a shallower face and shallow back design however its low spin seems to give it a piercing trajectory one that starts low and climbs steadily.

One customer who has both said the Aero launched lower for him.
