I'll try my best from behind the desk... Office jockey, away.. HA!.. Haven't had anytime on the decks personally so it will just be basic breakdown of construction and tech. Although that should change soon...
Hooke 38/42, Fastrack stance options: 21" - 27"
Hooke will be a aggressive 3 stage similar to the Recoil but with 4 added fir stringers near the center of the board and a carbon wrap rails for added strenght, increased pop, and stiffness. Also should hold its flex pattern longer with the add carbon. When I say aggressive its a really aggressive 3 stage, need to see it up close to really notice it. Looks like a killer wake to wake board! Tons of upward pop with those stingers so close to together! Skate ollie type pop.
Newton 37/42, Fastrack stance options: 21" - 27"
Newton will be similar in shape as the Respones and will have a continuous rocker layout. Added stiffness with the carbon wrap rails and 4 fir stingers near the outside of the board near the rails. This will allow killer loading of the board and the "recoil/rebound" with proper timing hitting the wake should send you to the moon... Will be the fastest of all the decks and should handle max speed and landings better with the added stiffness of carbon, proper placed fir support stingers and countiouns layout of the deck.
Kine 37/41, Fastrack stance options: 21" - 27"
Kine is the Reflex of the butch and as you guessed and runs carbon wrap rails and similar stinger postion as the Hooke... Very good pop from the flat, IE skate ollie. This board runs a hybrid flat 3 stage that makes it quick and nimble at low and high speeds. Chimmed rails too for catch free feature fun! Choice for those at the cable.
Hopefully my weak summury helps and to the knowlegde bank but I would assume SS riders will chim in as product drops! which should be very very soon...
