I'd say that the Creature should be weaker overall than the Kinetic, and have a more rounded breakpoint shape...the Creature should be a good, light-medium oil ball, whereas the Kinetic should be a very angular, medium-medium/heavy oil ball.
Hypothetically, and Bar could probably answer this or confirm it, I see the Break fitting above the Kinetic in terms of total hook (but maintaining a similar breakpoint motion on the proper amount of oil), and the Creature fitting under that...though there might be too much of a gap, in which case a smooth-rolling solid might be a great fit, like an AMF Hei$t.
You could have a decent little arsenal:
900G The Break
Track Kinetic
AMF Hei$t
900G The Creature
Hope this helps!
