My Radical is a fun ball to throw. Out of the box was too extreme for my taste. I've experimented with varying degrees of polish, but have pretty much settled on zero polish and about 2000 abralon.
This ball's strength is the versatility of the cover. From extreme skid/snap to much more predictable with less shine, or no shine. It can really cover the boards on the backend if you'll let it.
I wouldn't call it a heavy oil ball under any circumstance, but definitely a medium oil ball (2000 abralon) or a very strong dry lane ball (with polish).
Here's what Bowling This Month said after it's release: "The lanes have to be pretty dry for this ball not to perform... If you only want one or two balls, this should be one of them. Very few balls are as capable of handling a wide variety of lane conditions."
