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.

    Covert Tank

    Love the ball. Used it on all types of lane conditions. Haven't shot under 650 series with it. Start right with the ball and slowly migrate inside with it. The ball is very predictable, even while moving inside with the ball and with my feet.

    Oh my god this ball...

    I literally cannot say enough good things about the Covert Tank. It's been the ball of the year for me. I *depend* on this ball to give me a chance on any condition where the lanes are either drier or just super touchy wet-dry. House shots, sport shots, USBC Nationals even. The Covert Tank is my go-to when I need to know exactly what the ball is going to do. Especially with me getting around the side of the ball so much, my equipment tends to be pretty jumpy off the spot. On fresh or drier conditions, I need predictability more than power. Urethane doesn't work for me. It either rolls up too early or never hooks at all. Ball has already paid for itself three times over in two short months. I cannot wait to see what more MOTIV ends up doing with this new coverstock. I've never been this excited about a coverstock before but Microcell Polymer is truly special.

    Here's my video review of the Covert Tank:

    Covert Tank

    The Covert Tank features the Torx core found in the Forza line, and the all new Frixion Microcell Polymer cover that is NOT urethane or reactive resin. This ball will bridge the gap between resin and urethane, and will give bowlers with lower rev rates the look of urethane without sacrificing carry. I drilled mine pin above the bridge and compared it with the Venom Shock Pearl drilled the same.

    I tested the Covert Tank on a late night session after a league had finished bowling. With the previous Tank releases, I always had trouble carrying with my lower rev rate. The Covert Tank is like a previous tank on steroids. It rolls so smooth but hits and carries like a truck. When compared to my Venom Shock Pearl, I was about 2 and 1 left. They compliment each other very well. I also compared it with the new Ripcord and was about 4 boards left with my feet.

    I’d feel confident recommending this ball to bowlers who want that urethane look but may not have the big revs like the guys on tour. For those with higher rev rates, I feel this would be a great ball to get you to your urethane equipment.

    Covert Tank

    The Motiv Covert Tank, featuring the NEW Frixion Microcell Polymer cover stock, has really allowed me to thrive on drier or beaten down lane patterns. The cover stock has more length than urethane, with a slower response to friction than reactive resin, but with the continuation through the pins of reactive resin. The cover, combined with the Torx core, has made for quite the motion as we are seeing flare of 5-6 inches when drilled with stronger layouts. But, what does this mean in real world settings? On our summer house shot, which has slightly less volume, I am finding that my Recoil and Shock are too soon while the Shock Pearl and Hydra are too angular. The Covert Tank has allowed me to play a little more direct through the track area and chase left (right-handed) as the night wears on. The Thrill is a great compliment if the Covert starts reading too early due to transition. Also note, a shorter pin to pap layout on this ball will yield the more traditional urethane roll while a longer pin to pap layout will allow the ball to transition slightly quicker for a more pronounced motion at the break point.

    Game Changing Technology

    Motiv’s new release, the Covert Tank, utilizes the Torx core previously found in the Forza line and wraps it in a brand new coverstock- Microcell Polymer. This coverstock is completely new to the industry as it creates track flare seen in resin balls with the motion of a urethane ball. As a speed dominant player, this ball allows me to stay right a lot longer and play up the lane. It gives me the predictable shape of a urethane ball but with the track flare that doesn’t destroy the front of the lanes for the rest of our team. Mine was drilled 50 x 4.5 x 30 which allows it to be smooth and have enough power down lane to carry. This is a unique piece in the market and fits in everyone’s tournament bag.
