    Tenacity on Enhancers

    Posted by Todd Allred on Dec 31st 2018

    If you liked your Tenacity you will love the Grit. For me the Grit starts up about 36 inches sooner giving me a good 4-5 more boards of over all performance and absolutely no quit through the pins. Its a great ball on fresh medium oil conditions and compliments the original Tenacity perfectly. It allows you to chase the oil inside and then ball down to keep that same consistent ball reaction.

    One of my favorite balls no question

    Posted by Kelly Lake on Dec 4th 2018

    This ball revs up so easy and is beautiful to watch downlane. I drilled mine up 70x4x35 and I can count on this ball to make a good turn for me on heavy oil conditions. Just fired off another 300 with it yesterday. The Dynamicore technology is amazing and seams to carry any hit that is even close to the pocket. This ball will go down as one of Brunswick's finest creations!!

    More traction than the original Tenacity

    Posted by Jeffrey Poholsky on Nov 27th 2018

    After rolling the Tenacity Grit, you're going to think you're throwing a ball with snow tires on it. This ball really bites the lane and has a beautiful shape to the pocket. What's really great about it is that it doesn't hook early or burn up, it just powers right through the pins. For bowlers like myself that don't have a high rev rate and sometimes struggle getting the proper shape, this ball addresses those concerns above and beyond.

    Mine is drilled pin under middle finger. Oil does not challenge this ball. You can freewheel it and it will respond. A great piece and a complement to your arsenal if you run into a fair amount of volume.

    The Tenacity Grit is a stronger version of the original Tenacity. It reads earlier in the midlane area while still providing good backend recovery. This ball is not the earliest of reactions but is not allergic to oil. This ball will provide you with the ability to play in the oil and create angle to the outside part of the lane. So far, I have found the Tenacity Grit to perform best when my heavier oil balls are starting to be a bit too early. This one is a step down from balls like the Kingpin Max and the Quantum Bias. The Tenacity Grit also works very well when used in the oilier part of the lane on fresher house conditions. Overall, the Tenacity Grit adds versatility and continuation to the Brunswick lineup. If you are looking for length and continuation on moderate to heavier conditions, take a look at the Tenacity Grit

    Great Strong Ball

    Posted by Robert Raulerson on Nov 13th 2018

    Ball: Tenacity Grit
    Layout: 70x5x30

    The new Tenacity Grit is a good compliment to the original Tenacity when you need to see the lanes a little earlier yet still retain the hitting power aided by the Dynamicore. This ball with the out of box finish picks up in the mid lane strong with good continuation though the pins on med-heavy to heavy oil. It also takes to surface change well if you need to fine tune your motion. If you are looking for a good ball for the heavier patterns, this is a good ball for your bag.

    When the going get tough, show your GRIT

    Posted by Rob Johnson on Nov 12th 2018

    LOVED this ball. Earlier than the original Tenacity, its also smoother and more all purpose. Very easy to read and control. Drilled ours 90 x 3 3/4” x 35, our benchmark layout. When playing on oil it reads the midlane without jerking left if it sees some dry. DON'T FORGET THE DYNAMICORE! That gives it even better hitting power! Don't just believe my word though! Look at Jason Sterner at the US Open. He destroyed everyone on his squad with this ball!!
