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.

    When I found out about the Covert Tank, I was wanting this ball to work for me more so than any other MOTIV ball within our lineup. I have never matched up well with urethane equipment and with my 19.5mph speed, urethane balls on the right side limit my ability to shape the lane because of carry down issues I get from others using urethane equipment.

    This new cover stock, Micro Cell Polymer, soaks up oil at a fraction of what resin does yet still absorbs more oil than urethane. The Torx weight block allows me to shortened my Pin to Pap on this ball because the higher differential gives me the ability to have more track flare plus I get more back end motion too!! The Covert Tank has the predictability of urethane, reads the mid-lane like a traditional resin ball and gives me much better pin carry than a urethane ball does.

    I highly recommend this ball for the typical house bowler, anyone facing those wet/dry conditions and for those bowing on sport patterns.
