Is it really picking up earlier or are you just seeing a quicker response from the Fusion
I'm certain the Fusion picks up earlier. The Tour responds to friction further down the lane.
I will say the two balls are not drilled identically. The Fusion is pin below the ring, while the Tour has the pin directly above the ring. Otherwise, same drill pattern -- no weight hole. I don't believe there is enough difference in drill to account for the reaction difference I'm seeing.
I haven't touched the cover on the Fusion, while I've had the Tour at 1000, 1500, and 2000. But it doesn't matter what prep I've had on the Tour. It's still further down lane before it makes it's move. I was watching a friend who also has the two balls alternate between them in league last night. I was seeing the same relative reaction differences.
Look, I'm not a newbe. My last Regional cash was with the Tour. I understand the ball very well. It's the reason I choose the Tour over the Fusion when the mids started to go three games into the block. I'm not seeing things, and I'm not tricked by color.
