I was curious about the pearl urethane pathogen plague as well, because I wish there was something out now that could replace the old Natural Pearl or Supernatural. Those were true dry lane balls. The only thing out now close to that is Fever Pitch, which is much stronger.
An asymetric pearl urethane is pretty unique.
The good, but sort of bad thing about the "urethane" balls out now, is that they are either not urethane (Covert Tank, Badger Infused, Fever Pitch) or very aggressive urethane that wants to dig in. While I think overall this is a general improvement for some conditions, these balls are not good for control on lighter oil (if you have a high rev rate).
So this pathogen plague may fill in the gap, couldn't find any comparison reviews of it compared to the other urethanes.
I did recently have to get a new spare ball, ordered a mix and it had a small "made in china" sticker. Next time I went to practice the lanes where unplayable, had to use cyclone over 6th arrow, and practicing standing in front of ball return just isn't a priority now.
So just experimented with that Chinese made mix, and it just totally crushed the rack playing over 3rd arrow. I've had Mix before in a higher weight. this one seemed different, didn't realize I was getting such a good back up strike ball as well. I wish they would bring out this ball with a bit of a core. That would be the perfect light oil ball.
