Well it all depends on what you want from the ball Lay, you are comparing 3 different types of balls. (a particle, a low RG, a Strong Resin) The Oracle is gonna give you a strong read on oil, I do own one, and will not ever overreact if there is a hole in the pattern, but will burn up if there is not enough oil. The RSX has a high Diff and Low RG which will give you a great midlane read, but for TRUE oil, you will prolly have to alter the surface by taking it down to at least 1000 GRIT, if not 800. Which brings us to the Vertigo, which is remarkably similiar to the Oracle, but is not particle, which is great if you have slower ball speed because the ball will not burnout as quickly as the Oracle. But you will see a bigger Jump on holes within a pattern or when the ball sees strong backends. Hope this helps....
