I have the Counter Attack solid. It is on par with Roto Grips Hustle series. Very useful all around ball, especially for medium and broke down patterns.
I don't have the pearl yet. From what I've seen, it's a bit stronger than the Twist, though that Twist can be drilled to give a strong reaction as well.
I'm not sure that I would consider a Counter Attack pearl for the burn however! I would go with the CA pearl when my solid is standing up too soon on the dry!
One of the best new balls for the true burn is the Track Heat. When I'm on the burn I just use older, milder coverstock pieces like RG Pluto or Global Link.
