Additional product information:


A drastic departure from our traditional symmetrical core or symmetrical weightblock designs in the HP3 line, the asymmetrical RondureTM Core was developed in increase overall ball motion throughout the lane without the aid of an added balance hole.


Featuring our most recent formulation of eTraxTM solid coverstock technology, this cover is easily sanded or easily polished in order to meet your needs on a variety of conditions without losing traction and responsiveness to friction.


Engineered for those Medium to Medium-Heavy Oil conditions, we felt it was an absolute must to provide added core technology in this line in order to create advanced ball motion since balance holes are no longer legal in sanctioned competition.

    I purchased this ball for the nights when the lanes are playing uncommonly slick. I had Buddies put a 4x4x2 layout on it. Had I known how strong this ball was going to be I might have went a little less aggressive. Out of the box it is a hook monster. Factory finish is very dull. To look at it you may think 1000 or even 1500 grit though they claim it to be at 3000 grit. I ended up taking mine to my local pro shop where we put in the Haus machine and wet sanded it to 3000 Sair which shined it up a lot (it actually look like a 3000 grit ball). After that we hit it with a little polish and man did this ball come alive. Still a hook monster but very controllable. As matter a fact it is awesome on the fresh. With the new finish I also have to say it is very versatile as it respond to hand changes, angle changes and speed changes in a very predictable manner. I highly recommend this ball but keep in mind you may have to alter the surface to make it what you want.
