Comments:

Sound is the best of any driver I have ever hit which makes this driver feel great as well. Explosive feeling but not ear piercing loud. The Adjustability is a proven method and I am very glad to see it was continued in the EPIC. The only Appearance attribute that I would perhaps change is to have the speed steps the same color as the rest of the crown. That said it is a subtle difference that does not stand out much

Comments:

MUCH more forgiving. Consistently longer because of the increased forgiveness. I think the EPIC achieves more launch while killing spin. I have tried the head with multiple shafts and with each one have been given fantastic results. The performance of this head is unmatched by anything on the market today.

Long,Looks good, Best sound

CONS:

None

Summary of My Experience with the Club

Amazing feeling and Sounding Driver. Exceeded expectations in every way possible. Only small change would be to blend the speed steps a bit better by making them the same color. Overall the driver frames the ball perfectly at address.
