If your release/delivery specs in your profile are anywhere near accurate, that ball and drilling should handle almost ANY amount of oil.
Keep in mind that, in general, you should not expect to cover 49 boards of hook. This is not a big hooking ball, because the flare potential is only average, but the coverstock is very strong.
The bigger danger is that I'd be wary of not having enough oil. Your ball speed is not high enough to worry about the ball not hooking, but is low enough to worry more about the ball burning up in the midlane. If you're not getting enough backend to POUND the pocket, my inclination is to guess there's not enough oil, NOT that there's too much.
Reagrding the drilling: I might not have put the pin quite as high as you did, but with the CG where it was and the weight hole (hopefully, its position is 6" or more from grip center) where it is, the ball reaction should good.
Foppe is right the finish is a sheen. Do not take a burgundy pad to it. That is 320 grit that's way too rough. My suggestion is to take a grey pad to it BY HAND, to haze the ball more. test it then do it again if needed.
Again, this is a fairly strong cover with a very early rolling core.
