The ball is longer than the Blackout, with a more pronounced move on the backend. Sneaky strong if it sniffs the friction too soon. Real close to the Blackout and Euphoria if I played outside with it. When I moved in deeper, the Platinum had more length and would recover, whereas the Blackout and Euphoria wouldn't.
Now take into account that my Blackout and Euphoria are drilled with 85°x2.5"x40°, and the Platinum is drilled 85°x4"x30°. If they were all drilled with the same 85°x2.5"x40° layout, the Blackout would be the strongest because of more midlane. The Euphoria would be the weakest, with the most length. And the Platinum would've sat right in between both. Now if they were all drilled with the 85°x4"x30° layouts, I feel it would be the same results.
I like how all three compensate one another with my layouts. There was a slight gap in my arsenal between the Blackout and Dominion. The Platinum so far has filled it.
