Hi mate I have owned both boards over the past two years. The walden is a very stable board and a nice paddler but not a great surfing board and not the easiest board to paddle into waves. The Mct is not as stable but paddles ok and gets into waves pretty well. The Mct has a very very slippery deck grip and the handle is in the wrong place making it a pain in the proverbial to carry any distance - it is however a better surfing sup than the walden. In my honest opinion a walden 9.11 is the board for you. It will support your weight with ease and is amazingly stable and a great paddler and surfer and its light to carry. Over the past couple of years I have worked in the surf industry and this is without a doubt the best fun allround no b/s board I have ever ridden and owned. My wife has one and it is the sup I paddle and surf 90% of the time. Sure there are more high performance surfing sups (Laguna Bay for instance) but for fun fun fun go and try the walden 9.11. It is honestly ten times the board that the 10.10 Walden is and I think the same sorta price. Hope this helps.

Wicko, I have to agree with billboard.

I've only been SUPing for a few months on and off on a Walden Magic 10'10". It's been good to learn on, and paddles OK, and is stable, but it really doesn't surf well. I've ridden it in everything from 1/2 a foot to nudging 5ft. It's a boat for my 85kg. I'm hanging onto it to take the kids on flat water. As billboard says, paddling through waves is pretty hard on it (compared to my 9'6" Naish that pops straight over and through whitewater, the Walden literally ploughs and catches through any size wave). When you get going it struggles to hold a rail at speed, and the tail width makes it quite skatey. But, it has so much foam you could probably take the family out fishing on it, so it's not all bad.

I might have to try that 9.11 myself. Good luck.

cheers
