I think you should buy a sleeve of either Prov1 or Prov1x and go try them on you next round. Play on a slow day. When I tried them I went out late in the afternoon when no one was at the course. When you get to shots that are 100 yards and in play the ball you play now and a Prov. If you can't see a difference buy the time you either scuff them up until they aren't playable or lose them stick with what you are playing now.
If you want all the technical stuff there are so many reviews, just google it.
But if you are losing 2-3 or more balls per round it will make you sick to lose a $4 dollar ball. If I am not playing well I leave them in my bag.
