Mate, 6'1" @ 75kg here. Best board I've owned. Had an underpowered and overpowered sesh now after a week of owning it. It was down to this, the Axis Tranq and the Slingshot Asylum. They're all light and wake orientated but this being the tamest option has proved the best bet. I've lost next to no upwind performance from my freestyle board (135 best armada). It's a little skatey in chop when it's hard to hold an edge but totally worth the compromise. Just do it! 137 if you plan on staying in straps I'd say, but 140+ boards are where it's at for binded riding for sure. One mod I made to mine was to bolt on some axis slim fins so I could really throw it around and play in super shallow water (where I like to start from as I bind in). Just my 2 cents but it's really a top performer, I'm stoked, you will be too.
