Great roll and versatility in Mo’s first symmetrical core ball.

The Perpetual Motion is MoRich’s first symmetrical core ball and fills the space between the Mojave and MO’s recent asymmetrics (Craze, mania and RipR). The PM features a high density version of the Bruiser core most recently used in the Brunswick Monster Bruiser but first made famous in the Brunswick Technical Ventures’ Quantum line of premium balls in the 1990’s. If one tries to use a Raven Quantum or a Monster Bruiser on today’s conditioner volumes, one is met with skid, skid and more skid. But by marrying an excellent core to a modern super coverstock, MoRich has, in essence, resurrected the Raven Quantum ball motion for a new generation of bowlers.

My Perpetual Motion was 15 pounds, 3 ounces out of the box with 2 ounces of top weight and a 4 inch pin to center of gravity distance.  It was drilled 60 degrees by 3.5 inches by 30 degrees. No weight hole was needed. This is essentially the medium reacting layout specified on Mo’s simple suggested symmetrical layouts sheet. The difference between the medium and most-hooking layout is the addition of a P2.5 gradient line balance hole. My PM rolls great without the GLBH so it remains in the medium reacting layout configuration.

I have used my PM at box surface (500 Siaair, 1000 Siaair, Rough Buff Compound) and at 2000 Abralon/4000 Abralon as well as 1000 Abralon/2000 Abralon and 500 Abralon/1000 Abralon, on low and medium volume house conditions and medium and high volume sport conditions. The PM is remarkable in its versatility in being able to get to the pocket and carry with good coverstock to conditioner matches across this wide range of conditions.

The Perpetual Motion is not a replacement for the Mojave, 300C or any of the other mild pieces available. Likewise it is not a replacement for the mania, Invasion, Mega-Friction or any of the heavy condition specialists. The PM is a ball that will cover all of the medium-light to medium-heavy conditions with proper surface preparation. Out-of-the box, the PM is ready for medium-light to medium. I’m currently using my PM at 2000/4000 Abralon with excellent results on the light-medium to medium THS I encounter on a weekly basis. At 4000, my PM gets excellent length then makes a strong move (hook, not flip) late in the midlane with excellent continuation through the pins.

•   A good two-ball bag: RipR and Perpetual Motion
•   A good three-ball bag: mania, RipR, Perpetual Motion
•   A good four-ball bag: mania, RipR (or Craze), Perpetual Motion, Mojave (or Frenzy)

This is a great ball for all of the Quantum aficionados out there. There is an uncanny resemblance to the light-load particle and reactive Quantums: A 2010 update of one of the 1990’s most sought after shot shapes. The PM is also an excellent symmetric companion to an asymmetric arsenal. On days when your favorite asymmetric isn’t carrying, sometimes a move to a good rolling symmetric will be the answer (and visa versa).

Coverstock durability? 110 games into use of the PM, there is no discernable coverstock wear and no loss of reaction. The Perpetual Motion should be a good choice as a versatile, long-term tool in your bag. Way to go MoRich!
