This is the new golf ball being sold at Costco under the Kirkland brand name. The ball has sold out twive now at a cost of $39.99 fro TWO doxen balls. Pretty amazing price for a 4 piece urethane cover golf ball these days. The ball has gotten excellent review online. Report I read said it went 9 yard longer with 300 RPM less spin off a driver than the ProV1. Also spins more with a wedge then the ProV1 does, so thats a hard combination to best. especially for the price.
