I got to ride the new 131x40 and 136x41 FR today :) Rode them back to back with the Carved Imperitor 4 134, Underground Styx 135 and the Balance 135 Wide.
Nice looking boards - matt finish all over which is a huge plus for me, I hate smudge marks on boards... Nicely shaped channels on the bottom - square tips - and it's quite light.
Quad concave or 'Qattro' as Cardboards call it - smooths the chop nicely without making the board tooooooo spongy... Rides like all quad concave boards, soft landings and a bit draggy in the light wind.
Flex is pretty stiff, not Slingshot stiff, but stiffer than an Underground. Gives it good, sharp pop out of the water and keeps it riding fast.
Fins are a different shape to what we see on most twintips, rounded outline and quite a thin profile, The 135 has 50mm and 131 has 40mm, Good combo's - boards aren't too skatey, or too grippy. Landings are soft and the concaves help to get the board tracking again. the 50mm in the bigger board tended to catch a bit easier of course.
The footstraps are comfy too, stiff on the uppers today, but they'll soften over time as they get used. Lots of adjustment to make them bigger, and fitted snugly onto my size 8 feet at the tightest they go.
Rode upwind ok, not amazing but not bad. The same as an Underground FLX would...
It's got a nice cruisy feel, suited for the guys who are just happy to jump, do the odd kiteloop transition and blast about in the chop. Good price too at $900 with the 3 year warrantee, puts it competitively within the board range.
If you're looking to replace an old and battered board - or upgrading from your learners board - the 2011 FR would be a great choice. If you want a performance upgrade for more pop, or faster riding - you best choose something like the Tempo or Pro.
