I have little experience with Storm Equipment, but I did have a Barbed Wire punched up for a PBA Regional last summer. That ball is great for light oil. Also I was told the BIG HIT Pearl is good too. I've seen a few people use them as spare balls, so I'm assuming it would be good for light conditions.
Good Luck with your choice!
