A great competitive advantage in bowling today is modern urethane.  It provides bowlers with control and the ability to play different parts of the lane than reactive resin.  However, because urethane also has clear weaknesses, MOTIV® set out to create the ultimate cover material that harnesses the strengths of traditional urethane, but offers far more versatility. Introducing the Covert Tank. 

The revolutionary Frixion™ cover material MOTIV® developed for the Covert Tank is not urethane nor reactive resin. It is microcell polymer. Traditional urethane is virtually non-absorbing while reactive resin is highly absorbent.  Frixion™ microcell polymer absorbs oil at a fraction of the speed of reactive resin, but is still capable of absorbing oil at a very slow rate.  This microscopic difference creates more continuation and better pin carry without sacrificing traction. 

While typical urethane balls are primarily used by bowlers with a high rev rate, the Covert Tank is a more versatile piece that will benefit more styles of play because it merges this new microcell polymer cover with a strong Torx™ weight block.  The higher differential produces more track flare, which both improves backend motion and also limits oil redistribution.  Traditional urethane balls tend to have lower track flare, struggle with pin carry, and push more oil down lane.

Even the color scheme of the Covert Tank was created with the competitive bowler in mind.  The solid black cover with dark gray pearl NeoMark graphics provides a crisp contrast to the lane surface so ball motion is easy to see.

    So long urethane!

    When you look at this ball you wonder what's different? Well, let me tell you.
    First, it has a brand new kind of coverstock. It's not urethane it's not resin. It's something brand new and fits in between both of those coverstocks.
    Second, let's talk about the ball reaction. This ball will remind you of urethane in its overall shape. It's very rolly and doesn't change direction
    very quickly. It flares A TON more than a urethane ball, so that's nice if you love urethane but don't want to be a bad teammate wrecking the pattern.
    This ball will give you that shape without destroying the pattern. It also allows you to throw this ball on a multitude of patterns. Do your research, and it will show you how good this ball is! This ball will be a legend in its own time!

    I drilled my Covert Tank pin under the ring finger to hopefully create early roll but to hopefully gain more down lane motion and continuation than urethane provides. The ball exceeded my expectations and has become a staple in my arsenal. I can play straighter longer on short or light oil conditions. This ball is what every company is trying and failing to create with their reactive urethane mixtures. Best of all, I can use this ball without destroying the lanes in league like urethane would.

    Covert Tank

    This is the smoothest rolling ball I have thrown in a long time. It does exactly what Motiv says. Very smooth through the front part of the lane with a strong but controllable back end reaction. I got it for Father's Day and had it drilled today. Threw on our house shot, medium volume, 41 feet. Left lane had six games on it, right lane was still fresh. I played four and two deeper on the left than on the right. Great ball, especially if you're getting old like me and have lost some of your ball speed. But, I think a young, high-rev player will love this ball too!!! All I throw is Motiv and this is a great addition to a great line of equipment!!!

    Motiv Covert Tank Review

    The Covert Tank is a unique piece with tons of versatility in creating different motions. It has a bigger core mixed with the new microcell polymer cover, giving it almost a Urethane shape down lane, but reads the fronts like resin. I drilled mine with a stronger layout using a 4" pin which actually gave me a bigger flare than anticipated. But it lets me move in and control the lanes when the lanes start getting jumpy. It’s also a good piece for the flatter patterns when I want something with a real controlled motion. Definitely a game changer in ball Motion and not like any other piece in our line up.

    Motiv has created a new cover stock that fits between Traditional Urethane and Reactive Urethane. The cover is called Frixion Microcell Polymer. The intent was to create a ball that had the control characteristics of Urethane but enhanced performance to give it ability to be used by a greater range of bowlers. The Covert Tank flares more, and hits harder than Traditional Urethane. Normally when I use my Burgundy Tank I feel I don’t have much room for error. The Covert Tank allows miss area to the right with recovery and carries extremely well. I have used the Covert Tank on a good variety of patterns, and the ball motion is very nice. When I use traditional Urethane, I feel I need to move right as oil carries down. With the Covert Tank I can move left and create more area; this is most likely due to how the Covert Tank absorbs oil slow enough to maintain a better lane pattern. The Covert Tank is stronger than my Thrill but is weaker than my Venom Shock. To me, it rolls closer to Reactive than true Urethane. The Covert Tank reads the front part of the lane but still has a nice, controlled move off the dry. I have let my high rev and no thumb bowlers test the Covert Tank out and think it will be a great addition to their arsenal. The ball is very predictable and there is no over / under reaction. The Covert Tank goes through the pins with a strong, continuous motion. For someone like me who has limited use for the traditional Urethanes, I can see myself using this ball a lot, especially on house conditions. This ball should allow you to stay in the pocket as the lanes transition with very little adjustment.

    The Covert Tank has a Predictable and forgiving motion.
    The hit and carry was better than expected.
    This is a “Urethane” ball for those who struggle with Urethane.
    I feel this new cover technology has great potential.
    The Covert Tank should be a great addition to a tournament arsenal.
