Pinnacle is often the brand sold at country clubs as loose balls with a logo on them. At Pinehurst, recently, we were charged $3.75 each for these Pinnacle loose balls, even in quantity.
Pinnacles play nicely, and did well a few years ago in Consumer Reports' golf ball reviews. For 54 cents each when you buy 2 dozen, the deal really can't be beat.
As others have said, having a logo makes the ball easy to identify. There's also the "treasure hunt" aspect to going through them to find cool logos!!
