It's great to see, and mostly plays like regular 8 ball. Someone recently linked some matches with Chris Melling playing on one of those... one shot he missed seemed like it was due to the rounded pockets. But it was a tough shot anyway and was not unmakeable due to the pockets... just much harder. I don't think he'd even fire at it if he didn't have a planned safety built in.
I personally don't welcome any changes that make equipment play harder. When pool becomes too easy for me, and I start running out 70% of the time, then I'll worry about adding artificial challenge to it.
edit: just realized my little editorial must seem out of place. I was answering Scaramouche's question in the other thread...
"So, would Americans like playing on such tougher tables?"
