Any reason you want old school stuff over currently available balls?  Price, availability...?

Anyway, it really depends on how your center lays out the patterns, and which variation they use.  How many people are on a pair, what type of oil, the lane machine, your lane surface, and how worn it is make a huge difference on how they play.  Unless you've already thrown on them, don't automatically assume you need snow tires.

If you've seen my summer PBA log, I already bowled on Scorpion and Shark once.  Scorpion didn't play particularly long or heavy.  I pretty much threw a weakly drilled Black Widow Bite the whole night.  At this house, and medium strong ball with some surface could work.  Shark I used the Bite and a Weapon of Mass Bias.  WMB on the fresh, and the Bite when they broke down a bit.  Since we only have two bowlers on the pair, they don't change a bunch.  The second pair I moved to never developed a real hook spot.  With my revs and the lack of pattern break down, I might bring a third strong ball next time and leave the medium ball at home.  To answer your question (finally ), I plan on bringing out my AMF Angle Evolution Tour - one of the best oil eaters in it's day.  The was one of the few oilers that had a fairly angular back end which might give me the strength of the WMB and the back end of the Bite.  Just about all ball manufacturers have good oilers in their past.  It's really hard to say what might be available where you are.

NVD is Discontinued lol, it can handle oil xD

Of course everyone has an opinion... Well here goes mine. All the balls designed to perform on heavy oil over the past 10 years will still perform well on todays conditions. Its all about how you throw the ball, where your playing on the lane, speed, and so on...
 

  What I mean by performing is that you will consistantly find and hit the pocket maybe even better than with todays big hooking balls. Will you strike as much??? The answer would be no. For instant, take an HPH Zone and put it against a Ultimate Inferno and place both at the same surface. The Ultimate Inferno will carry at least 10%-15% more than the HPH will a game. Depending on the conditon of the lane, the Ultimate would carry a good 30% more strike a game vs the HPH.


  Now some people may argue with me all day about what I just said but just take a look at todays bowlers... Some rely on all that great carry, big hook, etc. because for one they sure as hell cant hit a mark twice. And for two they are able to play the lanes sometimes wrong because of todays ball technology.

  As far as a consumer buying older balls today... Why would you even think about this, mainly because some of the balls in todays era have dropped in pricing vs. 5-10 years ago. Uless you find one heck of a deal then its not worth it. I am going to use Ebonite for an example here. Two of some of the strongest balls ever are in Ebonites mid price line. The Pin Slasher and the Gamebreaker. You can get both of these balls for around a hundred bucks. Sure the NVD,etc. may hook a little more but these two mentioned can and will handle all the oil you will ever encounter. Hope you guys dont think I am to crazy here... John
