You have some options, for sure. I would recommend either Visionary's Blue/Green Centaur, the AMF pearl Angle, Roto Grip's Neptune or Lane #1's Chainsaw.
The Hammer Razyr is another option, as is an Ebonite Tornado and Brunswick Power Groove.
The Razyr, Tornado, Groove and Angle are all either pancake weight blocks or pancake derivatives. The Centaur, Neptune and Chainsaw all have "real" cores in them.
If you can find a Visionary Slate Blue Gargoyle, that's another option. It's urethane pearl, but discontinued. It's also not reactive, so it's going to have a different roll characteristic than the others.
Of the three "real-cored" balls, the Chainsaw and Centaur are going to be a bit more even, while I would expect the Neptune to be a bit more angular because of its cover. Typically, I would prefer a true dry-lane ball to be on the low side in terms of angularity because I don't want any surprises at the breakpoint, so if it were me, I'd probably opt for the Chainsaw or Centaur.
You can also get what you're after by buying about a 10-15 year old ball that was for medium light back then. Great deals to be had on eBay for those.
