Does anyone else have issues using blotchy tri-color solids like a Haywire or Inception? Must be a mental thing for me but rolling those throws me off some. I think it's because they look like they're rotating a lot slower down the lane or something. Just wondered if I was the only one.

I am with you on this.  Bold, tri-colors do seem to make the ball look like it is revving less than when using less colorful ones.  I believe it is a mental thing.  It's funny because I have used a few single colored balls that have two sets of labels and the double labels make the ball seem like it's revving like crazy.  Always feel better throwing those.

It's keeping me from considering the Inception because of my experience with the Haywire. I just start throwing it stupidly. 

For me it depends on the colors and how they blend if at all.

I'm more of a fan of darker colors as it's easier on my eyes to read. Once you add a color that pops, it can vary ball to ball depending on the pour

I can see the roll regardless of color scheme.  You always have labels and grips on solid colors even if you match the grip to the ball.  For me, I see a tri-color (Inception as an example) rolling a certain way off my hand based on the pattern of rotation and tilt.  If that starts to change because I am around the ball too much I may not feel it at release but I see it down lane.  You can definitely see the way the pattern scheme changes as the ball flares.

I do agree it gives your eyes the ability to see how it's reading the lane a little better than just the motion of the ball. It makes me think I have to hit it harder and leads to inconsistencies for me.

Multi-colored balls will often appear to rotate (rev) less than a solid colored ball.
This is because the markers most visible on a solid ball are usually the finger inserts.
In the old rubber ball days before inserts, most markings were located above the fingers. As with a solid ball, these markings are located much farther from the ball's axis of rotation, than are the multitude of marks and patterns visible on multi-colored balls.
Markings or swirls that are located closer to the axis of rotation will appear to be rotating slower because they are indeed, rotating slower than markings located farther from the center of the ball's axis. The best analogy is a phonograph record. A mark that is located closer to the center of the rotating record moves slower than a mark located near the outside edge of the same record. Both marks complete one full rotation at the same time but since the mark this is located near the outside edge has
much more distance to travel it has to move faster.
If you took a solid colored ball and placed a very bright marker close to the axis of rotation that MARK will rotate slower than one farther out from the center. However the rev rates (rpms) will remain unchanged for all points on the ball.
