I was just looking at the Mars and its coloring reminded me of the Ogre Solid. Both are orange and black - Pumpkins. (I started calling my Ogre solid, the Pumpkin, when I had it. Mine had a lot of orange in it.) Then, I looked at both balls' specifications: medium-strong coverstocks, with high RG core (~2.6) and low RG differential (.029" vs .020", biggest difference I see so far), and symmetric cores.
The major difference and a relatively trivial one to change is their stock surfaces. The Ogre solid is 600 grit US, while the Mars is 1500 grit polished.
I wonder how they'd compare with the same surface preparation and drilling. I have no present idea. I just wonder.
