A No Rules with polish would still be stronger overall than the Eternal Cell.  This would be due to the core strength and also having a much stronger cover.  The big thing to remember is that the Eternal Cell does not have the MicroBite or MicroDNA particle additive.  In that sense, you're getting more of a true medium to medium-heavy condition ball where you have a weaker cover but strong asymmetrical core.  The No Rules is where you have a strong core and a strong cover for maximum traction.

Compared to the Snap Lock, the overall reaction will be closer but not exact.  The No Rules with polish will get down the lane a little further but would still likely be a bit earlier and more even in motion.

All 3 balls complement each other pretty well.

I think it's all about core hook shape and what's going to carry those 10 pins!

I think the latter is 43 ft with 20 units.  I am a lower rev player high axis I believe.  I am more up the back of the ball.  Not much side rotation.  Want more of that.

What is a cell cored ball?  Curious of some examples.

The Nucleus core is still one of my favorite cores that came out of Utah.  Regardless if you have slower speed, fast speed, high revs, low revs, that core works for everyone.  I always enjoyed the heavy roll and hitting power that balls in the Cell line have.
