I'm going to give Radical a try. Was thinking of starting with a good benchmark ball for the left side (low rev), then moving up from there. In previous incarnations, I'd consider an Absolute Inferno a fairly good measuring stick, and believe the Torrid Affair would be just a bit up from that if the comments I've seen have been accurate...

Thoughts?

Hands down Radical's best ball is Untamed Yeti.  I'm left handed and can use it all 3 games in league. Great benchmark ball. I'm a tweener little more speed than rev's

Have to agree with the Untamed. I have drilled two of these for people. Both absolutely love them. The one guy bowls on my team, his is a pin down layout. Very clean with a strong continuous arc downlane. Very predictable.
