Roto Grip Halo Vision Ball Review

Layout: 70 degrees x 5 5/8" x 45 degrees

RG: 2.49"

Differential: .050"

Mass Bias: .018"

Surface: 4000 grit sanded

Core shape: Asymmetric

What I wanted from this ball: I was hoping for a heavier oil ball that will still backend quite a bit, with a fairly strong response to the dry boards. If this ball would shape similar to my Pro Motion but hook 3-4 boards more, it would be perfect.

What I ended up with in this ball: I didn't really get what I was looking for when drilling the Halo Vision. Instead of a heavier oil piece with strong response to the friction, I ended up with an earlier rolling ball that tractions in the oil and responds slower to the backend. Sometimes we read up on the marketing and put the "story" together in our head, and it just doesn't end up as predicted. That's the case with me and this ball. The slower response in the back has basically rendered this ball to more of a sport condition or wet/dry type ball that I won't be using too often.

The high differential asymmetric core revs up very quickly in the heads/mid-lane. I feel like the cover is just stronger than I anticipated. Halo Vision has far less length through the front of the lane than say an original Halo or Pro Motion. I'd put it closer to a Crux Prime type of ball motion, but with a softer response down lane. That can be useful when bowling on an extremely slick condition with fresh backends. I just don't see that regular enough to find much use here. I didn't try to change the surface on this one, as past experience here would tell me that it wouldn't meet the goal.

This one just didn't work out the way I wanted, so we'll move on to something different next time. While not a bad piece, we'll make sure to ask plenty of questions when recommending this piece from Roto Grip. We always want to make sure we're matching the right ball up to the right lane pattern/bowler.
