Aggressive Motion

(1 review) Write a Review
With MoRich's HUGE symmetrical core, they have created a ball that starts up in the midlane, and hooks a lot on the backend. While this ball was designed with medium to heavier oil patterns in mind, it also works great on longer, heavier house patterns and competitive oil patterns. The Aggressive Motion adds a very hooking symmetrical ball to the MORICH lineup.

    A versatile coverstock with an excellent core/cover match: Most useful on conditions ranging from medium-light to heavy, with medium-short to long pattern lengths. Box: 15 lbs 4 oz with 2.5 oz top weight, 3 ½” pin to CG. P500/P2000 Siaair. Drilled 60 x 3.5” x 30 with a P2.5 gradient line balance hole Whenever I travel to a new bowling center and/or bowl on an unfamiliar conditioning pattern, the Aggressive Motion is first out of the bag. I make all of my moves, up or down, based on how the AM reads the condition. Many bowling ball companies are touting their benchmark offering with one of them actually naming theirs the “Benchmark.” Rest assured the Aggressive Motion is the quintessential benchmark ball: A ball that is useful over a truly wide range of lane conditions and provides the bowler with accurate and easily discernible information about how the lanes are playing. Most importantly, the AM will provide a good look on a wide array of patterns. The 500/2000 box finish will not squirt through carrydown and the strong layout mated to the Level 3 super cover assure me that I can use the AM on any heavy and/or long pattern that your friendly lane man can put out. But I have two other heavy pattern specialists in the bag in the mania and the DestroyR. The Aggressive Motion is complementary to these when I use a 3000-grit or 4000-grit surface. The ball gets to the breakpoint without drama then zeroes in on the pocket with a strong and confidence-inspiring arc. True 3000-grit is my top choice on Anvilane, Pro Anvilane and Pathfinder; the harder synthetic surfaces while true 4000-grit is a great match on the textured synthetics: HPL, SPL and the like. On wood, true 4000-grit works well but 500/1000/Rough Buff is an even greater match for me. Compared to the Perpetual Motion, the AM is at least two boards stronger and, on heavier conditions, closer to four boards stronger. In both cases, the added strength is in the midlane. The Perpetual reads the back ends as strong if not stronger than the AM but the Aggressive Motion reads the midlane earlier and harder at any similar cover finish. Therefore, if you bowl mainly on lighter THS patterns, I’d go with the Perpetual Motion over the Aggressive Motion; but for a ball that is uncannily useful over the widest range of conditions, I’d choose the AM. Keep in mind that both of these symmetricals feature a strong engine, armed with a low RG and high differential RG. With the right drill pattern and balance hole, the AM will be stronger than many moderately strong asymmetricals but, again, with the right layout combined with no hole or a flare-reducing P1 hole, the AM takes on an entirely different personality that gets excellent length with a pronounced backend reaction that borders on flip (most accurately described as a controllable hard arc). In comparing the AM with balls from other manufacturers, I truly have a problem. The AM (and the PM) provide a look that doesn’t exist in any other recent ball. The closest comparisons with my AM at 60x3.5”x30 with a P2.5 gradient line balance hole aren’t even symmetrical; I see a lot of Motiv’s Cruel and Ebonite’s original Mission in the reaction and shot shape but without the fast response to friction on THS block patterns and the like. In symmetric land, Columbia’s Outburst and Resurgence come to mind: Particularly when I rolled the Aggressive Motion without the P2.5 extra hole. For those who are familiar with MoRich equipment, the Aggressive Motion is an excellent complement to the strong asymmetric Mo balls: Strong in its own right as a member of the symmetric universe. For those who are new to the MoRich brand, the Aggressive Motion is a key part of your arsenal: Whether your arsenal numbers one, three, five, seven, nine or 19.
