Not sure what your ball speed is, but judging ONLY from the BTM review of the Mars (and what I have seen of the core from the Pluto and the Neptune), the Mars seems fairly close to my SBG. My SBG, drilled not too differently from yours, needs almost medium-light oil to clear the heads. Pearl urethanes do not get a lot of length and this core is not weak. I don't think I'll be getting a Mars, mostly because, unless I see or hear differently from the BTM review, it's too weak a ball. My SBG and others cover what it can cover.
With the finish and polish you have on your Hy-Road, it hsould be identical to the stock finish. Their 1500 grit is US graded. Valentino's 3000 pad is P3000 grit or 1500 grit US, the stock grit level. Snake Oil has no abrasive, so when applied, it doesn't change the surface grit. But the final result depends on how you applied it.
