Received my new 2017 IS 107
very smick looking boards
Couple things you notice straight away compared to the 2016 is the new tail shape.
Very different looking for an Isonic . Looks like thy have added a little more vee up towards the front section of the board.

Had my first run on it on Friday
Wind was 12-17, Gear Gun GSR 7.8, 37 Fin
Strap posi Back/Back, Mast track middle
First thing you notice when compared to the 2016 is the smoother jibing, you can really hook into the jibe much quicker and tighter.
The board feels smoother in the chop and trims a little nicer when compare to the 2017.
Overall some really nice improvement's in 2017.
Really Looking forward to spending more time on this board.
