Brunswick's successful relaunch of the Quantum product line continues with the Quantum Bias. This bowling ball features high-density Quantum Mushroom High RG Asymmetric cores along with a thicker urethane coverstocks. This thicker coverstock offers durability, longevity, and massive hitting power. This ball is unique in that each core has a unique design to compensate for the gross weight of the ball, the core's dynamics, and the balls hook potential. The Bias uses Brunswick's ECA-XR coverstock formula and the all-white color gives a unique look as well as enhanced hooking power due to the traction additive found in Brunswick's white pigment.

The Quantum Bias is absolutely next level GOOD!  I have thrown many balls and most of the Quantum line.  This ball is UNLIKE ANY BALL I have ever thrown.  The ball motion and hitting power of this ball is just amazing!  The Quantum Bias is versatile and best used on heavy oil, with multiple layouts that will complement any bowler at any level.

Currently have the Pin and CG inline with the pin above my fingers, and the CG in my palm and the ball never loses hook or hitting power.  Questions may be asked about cleaning the ball, but most of the best cleaners, especially the cleaners from Genesis work very well on keeping the ball as clean as possible.
This ball is a ball you just have to see it to believe how incredible it truly is. #brunswickbowling, #dv8bowling, #radicalbowling technologies

Quantum Bias laid out 40x5x45 (pin over bridge) with no hole.  I laid it out fairly strong as I am a lower track player who likes playing through the puddle more than most, so it doesn't take much for me to shoot through the break point for weak corners with higher rg equipment. 
On the lanes the Bias has really impressed me.  The dull cover is strong enough to traction in a fair volume of oil, but the core isn't giving me that instant roll that my Kingpin and Max offer. 
With the Quantum Bias I get a little less than average length, some push through the midlane and a strong (but not flippy) move on the backend.  This reaction makes the Quantum Bias my ideal #2 ball once my scuffed up Kingpin Max rolls out for flat 10's. 

Our local house is really slick with Ice oil from a Flex machine on Anvilane and we dress 44' Big Ben for our upper mixed league.  All this volume leads to flat 10's on marginal shots with weaker balls, but the Quantum Bias has carried exceptionally.  It is dull enough to deal with the oil, but makes a strong enough move to kick out the corners.  I have also had success after a few games on the Women's 2011 US Open pattern in our challenge league.  The Bias allows me to swing the ball once the oil has carried down and not worry about skidding through the breakpoint.

Compared to other balls in my bag the Quantum Bias has me 3 boards right of my Kingpin and Max all due to length.  It is both a shade earlier and stronger down the lane than my benchmark Vandal Destroy.  The Bias has been a great 1-2 punch on medium- medium/heavy oil with my Method which is a quicker rolling core on a weaker cover (the Method I like better going up the lane, the Bias for a little swing).

I am a big fan of the Quantum Bias due to its unique ball reaction.  I am not aware of many dull high rg asym options on the market and its shape on the lane has been much appreciated in my bag.  The white colour is a little blah for me as it is tough to see the ball roll so I've swapped in black finger inserts.  I recommend the Quantum Bias for speed/rev balanced players looking for a ball to throw in games 2-3-4 in heavier oil.

The Quantum Bias is a very strong rolling ball. It hooks in every condition with ease, but is not as early as my Pitbulls. It is a great compliment to the Black Quantum when I need a little more hook.  The best part about the Bias is even as the lanes dry up, I can move left and not give up entry angle and hitting power.  This is a great overall ball that I can use on a variety of conditions.
