Fluff,
I have the SD-73 Classic. Mine is drilled pin over ring, 4-3/4" from PAP with the CG at 45 degrees with a weight hole. OOB (1000 Abralon) is too much ball at my center. I have taken it to 2000 Abralon and added polish on top of that. Much better length with this surface prep. I really like mine, but don't use it much in league. I take it with me when I go to tournaments. I like the ball. I think that with a pin down drilling and some surface (say 500 or 800), it will handle a fair amount of oil, probably just shy of heavy oil. Without the polish, it handled carrydown pretty well. If you want more info, feel free to message me. Hope this helps.
