The asymmetrical RondureTM Core is a radical departure from the traditional symmetrical core and symmetrical weightblock designs in HP3 lines. It was created to increase overall ball motion in the lane, without the need for an additional balance hole.
This cover features our latest formulation of eTraxTM Solid Coverstock Technology. It can be sanded or polished easily to meet your requirements in a variety conditions, without losing traction or responsiveness to friction.
We designed this line to be used in medium-heavy oil conditions. This is because balance holes in sanctioned competition are illegal and therefore we felt it was necessary to include additional core technology.
Comparsions With Other Roto Grip
Roto Grip Rubicon bowling ball newest HP3 line includes the Rubicon, which is the only asymmetrical offering.

Overall ball motion throughout
We are now using a HP3 line the asymmetrical ball for Roto grip. They are a punch above their weight, as usual. The Rubicon is a big ball. The eTrax S20 solid reactive cover is more traction than the eTrax S19 on the Idol Pro. It doesn’t feel like the ball will blow through the spot. You can trust it in this regard. Keep going until you find the right angle and coverage. It is a mild asym, and it shows. It has the characteristics of both a drilled asym and an asym, in that it changes direction strongly but remains fairly constant. I needed to find the spot that was between the 4th and 3rd arrows.
The Rubicon felt stronger than I needed on this medium-sized house shot. It was causing me wrist pain, so I had too much axis rotation. This made it especially hard to get off the spot. The Rubicon looks very angular, but it is actually capable. It never failed to hook enough. It was all about moving forward until I found it. It was at this point that I was able to break it enough to lose my carry with flat 7s. This is again a result of too much axis rotation.
As always, though, before you put a ball in your bag, think about how you play and what you like to bowl. This ball was as strong as the UFO, I thought. The truth is that the UFO has more natural traction using the Micro-Trax, while the Rubicon has greater responsiveness with eTrax. However, I couldn’t help but wonder if I could actually have both of these balls in my bag. I don’t see any Rubicon connection to the Idols, other than the fact that they are all-round bowling balls.
Idols are smoother than the reading Idols, which have a smoother and earlier appearance. These shapes can’t be replaced by the Rubicon. They are completely different beasts.
Sean is testing the Rubicon. Sean has a higher rev but is also able to control his Axis rotation better during testing. The Rubicon was a great choice for Sean. This is where the conundrum begins. Sean has never been one to enjoy strong asyms. They can be too difficult and excessive to push through the heads while dismantling the pattern. He is comfortable with pearl asyms, and his current favorite is Storm AstroPhysix. He was able to move the ball smoothly and clearly, and it was easy to read.
It reminded me of an Alpha Crux, where he can push it down and it will come back. He was a beautiful sight and could get deep without losing hit. No problem with the 4th arrow. He also tried the more direct shot, which he said was around 7 to 3. He also tested the Rubicon. It was actually something he said that I didn’t know, but it made sense in relation to his arsenal. It was his Storm Drive and AstroPhysix, he felt.
It is easy to see why it makes sense. It has the Drive’s midlane read, but the downlane motion from the asymmetric AstroPhysix. The Rubicon was able to stop the Drive’s almost continuous jumping and stopped it from going too fast. Although it can’t push as hard as the Astro, the Rubicon can still create the angular shapes it needs.
Roto Grip Rubicon bowling ball now has an Asymmetric option for HP3 Line. The ball was too young for me so I decided to go with a long and strong layout. The ball’s R&D team was spot on.
The Rubicon falls somewhere between the UFO and Idol but is cleaner than the Idol. The Rubicon is somewhere in between the UFO and Idol, but it’s cleaner than the Idol. Before I settled on the Rubicon, I tried many balls. It was simpler than other options and more comfortable to hold in my hands
Roto Grip is a strong contender for the Rubicon, according to me. My opinion was that I would not immediately think I needed anything stronger than the Rubicon. I placed it in the Strongly Defined category. What happens to my UFO? We are still not sure. It fits right in, but it is very usable. This is the type of ball that Sean can use to block the more difficult shots in sports. Will you cross the Rubicon for history enthusiasts?

Ball Roto Grip Rubicon now offers an Asymmetric option for the HP3 Line. It includes the Rondure Core. It is designed to reproduce an asymmetrical core with additional mass that has been removed by a weight hole. This idea worked well with the HP4 UFO. This ball maybe even more appealing to me.
E-trax 20 covers are all about versatility. It can be used between earlier and later E-trax versions and responds to surface changes. This was my first attempt at an Asym in the HP3 HP3 line. I was concerned about the ball being too young so I chose a strong and long layout. It turned out that I wasn’t worried about it. The ball’s R&D team was absolutely on point.
The Roto Grip Rubicon bowling ball is somewhere in between the UFO or Idol, but it’s cleaner than the Idol. It also has a more responsive down-lane. It was my first time having it. It was my first time throwing it, but I did practice it. Because of the steep angle through the front, the shot was extremely cliffed. The ball I had was not slow enough down-lane to eliminate the angle. I tried several balls before I decided to stick with the Rubicon because it was easier than some other options and smoother than others. It is very versatile and can be held in your hands.
If there were oil patterns that had a bit less shape, I would have chosen an earlier layout. The idols came very early for me, so I wanted to make sure that I was able to get the ball down-lane. It’s something I enjoy so there’s a 99 percent chance that a second one will end up in my tournament bag with an earlier layout.
