This is a symmetrical solid bowling ball. The numbers at 15 pounds are 2.596 RG with 0.020 differential. It is not reactive resin, and the finish is 500-1000 Siaair micro pad. The Brunswick U-Motion features the solid urethane coverstock, the U-Motion core, and the color is deep dark purple. This one is different than the True Motion, and it is all on the specs, so we’re going to jump right into it. Now we are looking at the Brunswick U-motion, a solid urethane from Brunswick. It will let you play a little bit straighter and give you that true urethane shape. On the other hand, the pin-down Motive Purple is incredibly smooth. The pin-up one does not boom down lane like other reactive resin balls or like the microcell balls. As a result, this ball will hook early and stop and be very smooth down lane.Ĭompared to the Desert Tank, the pin-up Motiv Purple Tank actually wants to slow down and stop down, which is a good sign. With the pin-down Purple Tank, I went with a solid pin to path and a very high VAL (Vertical Axis Line) angle. I wanted to make sure I had the same layout to see the differences between them. The pin-up Purple Tank urethane bowling ball is the same layout that I have on my Desert Tank. And the layouts on my two Purple Tank I have are 45x4x25 and 45×3.375×70. This ball comes out of a box at a 1000 grit laser scan sand. This is your true urethane this is not microcell. Then wrapped around that flux core is the purple urethane cover. The Motiv Purple Tank features the flux core, an RG of 2.57, and a max differential of 0.015 in 15 pounds. Now that you know what this urethane bowling ball is capable of, you can bring this to a tournament on a shorter pattern and be really confident that you have found something that will fit the bill superbly. It definitely starts up nice and early and goes through the pins really well. It does not have that sharp motion like a reactive wood on a shorter pattern. This ball also over hooks the Pitch Black by four to five boards easily.įast Pitch is renowned for its continuation through down lane.

It’s nice and round like a true urethane, starts up early, is very smooth and continuous. We chose this pattern because the urethane bowling ball typically looks really good on shorter patterns and not so good on medium to longer patterns.Ĭompared to the Pitch Black, the Fast Pitch Urethane Bowling Ball actually hooks quite a bit.

The oil pattern that we have chosen for this is Pegasus 36 feet. And possibly hook a little bit more as well. The Pitch Purple had a bit of a reactive blend, so we did not think that would be a fair comparison for this article.Įven though Fast Pitch and Pitch Black are both urethane bowling balls, you can expect the new coverstock on the Fast Pitch to be a little bit further down the lane and a little bit more continuous through the pin deck. Okay, so we are going to compare Fast Pitch against Pitch Black today because both of these are true urethane. So, all they have done is wrap Fast Pitch in a new coverstock. However, the Tour Block Core was also found in the Fever pitch.

The Fast Pitch features the Controll XL Coverstock and the Tour Block Core.
