Fins were ok, I felt the liveliness in the fins were weak. I may be too big for this fin, but bottom turns wouldn't hold so well.

Used thruster mainly, quad on the really small days. I am a big guy and these held nicely through turns. Just bought the nubster for the quad set up.

They seemed a bit larger then I am used to. Though very fast, I wasn't feeling the snappyness off the top i am used to.
