Hello, i'll try to help with this one.
I'm not sure if the price is good on it or not, as i'm not familiar with Aussie pricing, but I do know somethings that can help.
If the lanes are a bit oily, then out of the box, the Venom will not help you with this one. The only way the Venom will help you out is if you sand it to about 2000 grit abralon right when you drill it, and to drill it with a somewhat stronger layout. I'm unsure of your PAP, so I cannot suggest a layout, but with what I just said, that's the only way you'll see a nice, desirable movement out of the Venom on more oily lane conditions.
Also, if you want a ball for oily conditions without having to do anything special to it, look into getting a Hammer The Sauce. It's a brand new release, and is MADE for oily lanes.
Hope this helps!
