From what I have read the IQ Tour is earlier and a little less on the Backend when compared to the IQ Tour Fusion, plus it can handle a little more oil than the Fusion.

If I like my Fusion, would it makes sense to drill the Tour up the same way for when I see a little more oil or need something not as sharp off the Backend?

Or drill the IQ Tour different from the Fusion?

Right now the Fusion is 45 x 4 x 45

Thoughts please

I had both balls drilled with the same layout and same surface. The original Tour was much smoother and more predictable on the back end. I found that it was amazing on a down-and-in shot. My Fusion covered more boards and was better for playing deeper lines, though I wouldn't consider it a coast-to-coast ball by any means.
I definitely think the original Tour would be good for when you don't need as much recovery.
