Here are a few words I just posted on KF regarding the Zen Wide for heavier riders:
I have both the Zen 129x39 and Zen Wide (135x43) and they are both really smooth boards. These are the first wood core boards I have ridden which seems to make them a bit heavier then the Flexifoil board I normally ride but translates into performance on the water.
Regarding the wide - this is really fun board…it doesn’t seem to have a top end on its wind range, I had it out in 25-30 knots on flat water the other day and the pop was great but it was the landings that were unreal….the wood core just soaked up the landings no matter how hot you landed - it just seamed to absorb the impact without losing any of the power - very smooth. Also the width makes it easier to stick a move and ride out of it without loosing speed.
I think for heavier riders this board is ideal and importantly has enough core stiffness not to lose its riding characteristics with a 200+ pound rider in higher winds. Otherwise it turns great, edges/pops really well and has a very gratifying “tuned suspension” kind of ride. Also, I would not want to see what kind of force it takes to break this board.
Good luck - Feel free to pm me with more questions.
