Additional product information:

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.

    It's hard for me to say that I am impressed with a ball immediately but this new Covert Tank made me say just that! The new Microcell Polymer Coverstock is so unique that it really has a chance to make a big market impact. To me, the Tank has urethane like consistencies in its roll but continues and reads the midlane well like resin. What's so amazing about it is that it has that urethane predictability but I was never afraid to move left with it and open up the lane. It's continuation is super strong for me. My first night of league with it, I was able to use it for all 3 games without losing it's hitting potential while having 3 two-handers on my pair disrupting the oil quite a bit. The Tank just never saw the transition as much as a traditional resin ball would and it allowed me to be in the same zone on the lane for almost the entire night. For anyone who bowls on wet/dry conditions, typical house shots and sport patterns, I believe this is a must have ball. I drilled mine 45 x 5 x 30 which gives me a more angular motion down lane. Those who want it to be smoother can drill it with the pin closer to their axis and to give the ball a more urethane dominant feel to do a 0-2" pin to PAP.
