I was just down at Mort's tonite and played a few games with the red 5hr balls. They definitely play a little different. They don't seem as grippy as a nice sanded up old pink ball. I think the plastic is a little bit harder so even tho they're nice and scruffy, they aren't as grippy as you'd first think. I didn't test for roundness, but they do look like they roll a little weird sometimes. I think they're probably round but with the extra fuzziness they might be sliding some as they're rolling so they don't look like they're rolling true. Just my initial impressions.
I liked them for passing and single man shots didn't need a lot of adjustment but more complicated shots I was having trouble getting a feel for them. I do a lot of reverses off back pins and those were mostly the ones giving me fits. My long pull was surprisingly good with them - fast, long, hard, and dead square. I got a few to take home and practice with, I think I'll end up liking them once I get a better feel for them. Better grippy than slippery
