So I put these HVC-L balls into play today during my round and they honestly performed about as expected. They showed no ill effects of their long shelf life but they also didn't wow me with their performance in terms of feel or spin. Since I was playing with my son (age 14) and my father-in-law (age 70+), I thought I'd get them in on the act so I gave them a sleeve. Pops even read the description on the sleeve of balls and said "This sounds perfect for me!" This was a new course to all of us and wouldn't you know, we all found the water on the par 5 first hole! Good thing I had an entire dozen. The ball did not have excess spin off the driver and distance was equal to other balls in its class. The spin on well struck iron shots was lacking- had longer putts on a few holes because it would roll out 10-12 feet at times. The feedback from short game shots was not as good as newer models either and I had chip, pitch, and sand shots all in the first 5 holes. I don't think I hit a GIR until 6th hole. My son and I both prefer a urethane, multi-layer ball so I doubt I'll be putting these into play again soon except on water holes. Pops plays a 2-piece distance ball all the time and he said he couldn't tell any difference, good or bad, so he might just get the remaining sleeves.
