Guy at my local pro shop gave me a sleeve to try out, and Yes, for the $$$, or even compared to the higher priced balls, the Duo is well worth trying.
I am 63 years old and carry a 3.6 HCap. I was previously a golf ball snob so to speak and would have never dreamed of using a Pinnacle. I've lost significant distance over the years and have just recently started using the Pinnacle Gold and have found some of that distance. I also find sufficient stopping power on full shots to the green and short game is unaffected. I am quite pleased with the new Pinnacle Gold and will continue to play them.
