They have made 3 two peice urethanes thus far:
Red Sorcerer
Glowing Amulet
Slate Blue Gargoyle
You can find info on the two older balls on the closeout section of there website
www.visionarybowling.comAnother 2-piece urethane is due out end of this year/beginning or sometime next year!
They make unbelievable durable urethane coverstock equipment that hits hard and it suits them perfectly as they are the remains of Legendary Faball.
As long as they have one available in there lineup I am a happy man
I will say that the original Centaur though not urethane has a similer reaction it is a bit stronger but still has a nice smooth rolling arc
