Realize that the old original Cuda had, I believe, Columbia's Flexcel cover stock which is consider very mild by today's standards.
The closest balls that match it are probably the AMF Scamp, Columbia Piranha (with slight polish) and the Track Dry Heat.
There are several balls that have the equivalent performance on today's heavier oils: Messenger Ti solid, Messenger Ti Traction (with slight polish), Track Crunch, DynoThane Vendetta Black, Brunswick Bruiser are all excellen tmedium oil choices with good power.
