Prepare to be blown away by the newest limited-edition release from MOTIV, the VIP ExJ Sigma!  Collaborating with Triple Crown winner EJ Tackett, this special ball features a pearl cover wrapped around EJ’s favorite core, the Sigma core. This core, handpicked by EJ himself, boasts an unparalleled compact design that delivers easy revs. Coupled with Dynamic Infusion Pearl Reactive cover stock technology, this fast revving, medium oil pearl is as versatile and dynamic as the bowler whose name it carries.

The Sigma core is one of the first core designs ever created by MOTIV bowling. This fast revving, medium differential core provides outstanding control and down lane arc with many drilling options to customize the ball motion for the bowler.  Ideally used for medium oil, stronger drillings may provide enough track flare for bowlers to use the VIP ExJ Sigma on higher volumes as well.

The Dynamic Infusion Pearl Reactive coverstock previously seen on the Sky Raptor, was slightly modified to be slightly stronger in the oil in order to create the motion EJ wanted to see from the VIP ExJ Sigma.  This tweak gives bowlers more control of their ball motion while maintaining enough angle down lane to use the VIP ExJ Sigma when a low rg pearl is the right play.
EJ's discerning eye is not to be overlooked, as he specifically requested a ball that blends beautifully on the lane.  The stunning color palette of violet, purple, and black pearl were selected for the cover along with pink and silver pearl for the NeoMark logos.  The pearl VIP ExJ Sigma makes a bold statement on and off the lanes. 

When to Use

Speed Dominant Bowlers - For those whose speed overwhelms their rev rate, the VIP ExJ Sigma is a great pearl for later in the day when it’s time to start moving left.  Speed dominant players are often those bowlers who need to be in stronger balls longer than other bowlers.  For those bowlers a low rg pearl with moderate differential makes a lot of sense for late in the block or possibly a second shift league.  

Balanced Bowlers - Balanced bowlers will love the versatility of the VIP ExJ Sigma. This ball can be used as the go-to pearl in a balanced bowler’s bag.  When some help is needed through the front of the lane, but you still need some control of the lane this is the ideal ball.  

Rev Dominant Bowlers - For the Rev Dominant bowler who seems to always need a pearl cover because stronger solids just seem to start up too early, the VIP ExJ Sigma is likely the benchmark ball. Bowlers looking to build an arsenal of balls that are clean through the fronts will absolutely need the VIP ExJ Sigma to use as their benchmark ball on most moderate conditions.

    First game out of the box 279 with a 730 series! I went 40 x 4 x 30 layout. Out of box surface for now.

    This ball blends out the pattern well when needed. Missed left with it and it came back pretty hard and crushed the pocket! Another winner from Motiv! Thanks Motiv for the best and long lasting equipment!

    Don't Hesitate

    Had my pro shop guy order this EXJ VIP Sigma ball and stashed it for a while contemplating the drilling on it. I recently had 2 carpal tunnel surgeries in 6 months I averaged 178 for two weeks in one of my leagues and 172 in my other league. I decided to drill this a little weaker than some of my other Motiv Balls. OH man was that the right choice 60x4 1/2×40 in 2 leagues since I drilled it I've had back to back 650 series. If you can get your hands on one still Get Yourself One.
    My overall bowling game Is coming back to me after surgery and I can't wait to throw this ball again.

    Thank you, EJ Tackett

    Since I started throwing Motiv equipment in 2012 ( was a Brunswick guy for 43 yrs), my favorite has been the Sigma. Having a new ball with the Sigma core has been a godsend.

    This Sigma is the real VIP!

    I already have the ExJ OG VIP and the VIP Affliction, so picking up the Sigma was a no brainer. Gotta keep the family together, ya know! Well this turned out to be more than just a family buy. I really love the back end continuation on this ball. It revs up in the midlane snaps back to the pocket and goes looking for 10-pins in the pit buffet! I have it drilled fairly neutral with a 60 x 4.75 x 30 layout with the pin above my ring finger and my PAP = 4 5/8" right & 1/2" up. I've not gotten my revs and ball speed measured, but I believe I am around 14-15 MPH and 300-350 RPMs. So, I don't throw fast and I don't hook it a mile, but I can typically get it spun up enough to throw a few messengers. This ball LOVES to send messengers. It is definitely worth the buy and try! Get one before they're gone!

    Sigma core is best core!

    It is no surprise that EJ Tackett decided to bring the Sigma core back. It is one of the best Motiv has made.
    This core and cover combo gives something really special. It is incredibly clean and consistent; it really blends out the lanes when they get messy.
    The only negative thing I can say about the ball is that it is limited. Here's to hoping Motiv brings the Sigma core back into a catalog release soon!
