I wonder what the "Hybrid urethane" is:
half pearl urethane and half solid urethane (Think Storm SuperNatural),
OR
half urethane and half resin (Think new/current Hammer Blue Hammer)?

The 900G web site now tells the story:
80% urethane, 20% resin.
From the appearance of the picture on the web site, it seems like the urethane is a pearl urethane, but that could be just the looks of it.
In any case, it is ROUGH, 1000 grit.

So now we have the Shadow Ops, 80/20 urethane/resin and the Combat LE which is 50/50 pearl/solid urethane. Will there be much difference in the reactions? I know one is sym and other is asym.

For the Shadow Ops, which color is urethane and which color is reactive?
Is it the silver that is the urethane and the black is reactive resin?

I feel it is unrealistic to produce a "hybrid" bowling ball with the colors representing the quoted materials.  This would require a precise pour in order to provide a consistent reaction. 

Imagine the Storm Frantic


It would appear to be impossible to have actually different materials representing the two colors and have a consistent reaction ball-to-ball.

My understanding is what we perceive as pearl in a ball is an additive that affects appearance only.  The entire coverstock is the same material blended however is needed to achieve the reaction.  It may be 80/20 urethane to resin, but each color has this same mixture.

How do you know what you stated?  Do you work for Storm or other ball manufactures?
It's not that I don't believe you, but what information do you have to prove your statement? 

Phil Cardinals has said in videos that it's all about the additives used. Same reason for why not all pearls are long and flippy or all solids are early
