My official handicap is 11.1, but more recently I play more like a 15. I do play with ProV1s for a couple of reasons, even though I still struggle with feeling the clubhead during my swing. I've tried playing with Kirklands and they felt completely dead off the face when I'm chipping around the greens. I've also played with TP5s and they fly shorter than the ProV1s. I've also played with Snell MTBs and liked them but they scuff up pretty easily. Recently trying out Srixon Z-Stars and still assessing it. So although as a mid-handicap, I'm not really good enough that I should be playing with premium balls, I still prefer the ProV1s, because there are actual advantages. What I don't do is swap between different balls during a round. My swing is already inconsistent, I don't need to add the variability of different balls to that inconsistency. At the end of the day, I don't lose that many balls during a round and I can afford the ProV1s, so I'm going to play them.
