I threw my new Forza SS for the first time last night. It's a bowling ball. Not a bad bowling ball but not a "game changing" bowling ball either.
Is it a "must have" in your bag? No, not if you already have something similar to it like a Revolt Havoc or Forza GT which are pretty much the same ball motion. The SS would sit directly between these two balls with the same shot shape and strength and honestly, there isn't that much room between those two balls anyway. It would be a decent replacement for either of these two balls if you happen to need one.
If you have the Chronic Paranoia, you probably don't need the SS either.
However, if you need an even rolling solid that can handle some oil with a predictable down lane motion, the Forza SS would be a good choice and it's a good value at it's price point.
Sorry Motiv fans, I would have loved to be all geeked up over this ball as I love the Sigma Core. Perhaps I will change my mind after throwing is a few more times, but my first impression is a just "meh, it's usable."
