Not only have I ridden 2016 demo allwaves, 9.0 and 9.4 I brought one :)
I went from a 9.5 LTD to the 9.0 LTD, Im about 105kg and 6.2, (work out my age from my profile name)
I first demoed the 2016 LTD 9.4 about 2 months ago, I have been using quad fins in the 2015 board and did on the demo.
I found the 2016 to be a Major step up in performance, its was smoother on the wave, bottom turns faster, responded quicker in change of direction.
It paddles faster, easer to get moving.
It felt a little less stable as the deck is a little rounded to allow for the thinner rails.
I went with the 9.0 as I wanted to improve my surfing and the 9.4 seemed a little "corky" (I hate that term but it just felt that way)
I picked up the new board last Friday after work, went out Sat morning off shore clean 2-3 foot and arvo in onshore slop to get a feel in choppy conditions, and again Sunday morning.
Im happy with my choice, happy I went smaller.
