Timmy Patterson's thruster is an updated version of his longtime thrusters.  The upright template will allow for tighter turns and more progressive surfing.  These fins have a fairly wide base and medium sized tip for drive and control while keeping the looseness to perform more radical maneuvers. 

The Timmy Patterson fins are part of the Pivot family
 
These fins are only compatible with Futures fin boxes
