So, I found a few of these Platinum Dots in FL at worlds. Today was the first time I'd ever hit them. Here are my thoughts:
They should change the name of these balls to "Ego Strokers". Platinum Dots are built like Tattoo NX3s. Just a molded polyurethane ball with no cover. The balls are slightly smaller than normal 12" softballs. You notice it immediately when picking them up or comparing them to other balls.
The Platinum Dots have a heavy, hard, rubbery feel. These are NOT balls I'd use for BP with any bat I cared about. I almost feel like these things would destroy today's bats fairly quickly. They don't have the harsh hard feel of a ZN classic M, but the smaller size and heavy weight are noticeable when you hit them.
Distance is simply incredible. That's why I say these balls should be called Ego Strokers. They come off the bat hard, and fly like absolute scuds. I was hitting this Platinum Dot harder and further than stadium balls. They penetrate well and end up much further along than you'd think. I think my top distance with the Platinum Dot (using an old Easton SCN12) was 410' or so. I don't know if I can even state enough how utterly long these balls are. I'd put them in the very upper echelon of distance compared to any other ball in existence. If I had to guess at the cor/compression of this ball I'd say something like .50 450. Hard, yet bouncy.
Again, these probably aren't balls you want to hit if you want your bat to last. They're heavy and I don't feel like they come off the bat lightly. Put a little backspin on a Platinum Dot and it will deliver absolutely jaw dropping distance.
At least they got the Platinum part right. These will outfly any other color Dot....
On a side note, I also had a Tattoo NX3 spinner in the mix. It has a green and yellow cover. This ball is extremely similar to the Platinum Dot, but isn't as hard, heavy, or small. Its actually regular sized. The NX3 performed well, but came off the bat lighter than the Platinum Dot. I'd put the NX3 spinner at about .48 400. I wouldn't use any broken in bat on these, but they're still a lot less harsh than Platinum Dots.
