I'm a super high handicap, who plays 36 holes a month if I'm lucky. Normally rotate between a ZStar XV or Maxfli Tour X (opposite end of the compression scale of what you're comparing here).
After reading your thread I decided to dig through my "found" balls and pick out a few 2 piece low compression balls to see the difference. First up was a Srixon SoftFeel. I played the entire 9 with that 1 ball (rare for me) and played one of the best 9s I've played all year.
My miss is a slice and there were a few shots that were a few yards from being OB, that I'm pretty sure would have been OB with a higher spinning ball.
Knowing the ball wouldn't spin, I committed to playing as many chip shots as I could low and running, which is probably better for someone of my skill level than attempting the high, fast stopping option.
The course was wet so I can't comment much on the distance, but I never felt way out of position.
Am I saying the 2 PC soft ball made the difference? Not entirely, in fact I'm sure if I committed to the "easier" chip shots with a premium ball I would score better. But the low spinning ball made me not even attempt the hero shot.
I did miss several putts short and missed the firmer ball off of my insert putter. The greens were soaked so I wouldn't blame that all on the low compression ball. In the past I've liked firmer balls off of an insert putter and softer balls off of a milled putter, but that's probably a mental disease.
So thanks for starting this thread, it's good to get a reminder to try something different and be surprised.
