Hi Christopher
And welcome to the breeze

Also being larger in bones, similar thoughts to Sir Cartoon, but i would like to throw into the mix the Angulo Shaka, which is my choice for everything that doesn't involve beach break waves, so race, open ocean, distance, runners DW etc.
The other option had I not been able to secure the Shaka was the Laird Coastrunner. It was just a little slower and wasn't going to catch runners as well IMHO
I tried the Starboard Open Ocean, and struggled to stay on it in the smallest swell and about 8 mths later, have paddled a Fanatic and whilst i did stay on, that was in a very gentle bay with little to know swell, wind or chop.
Personally I like a 30' wide board, and the idea is to keep on it, rather than get on and off it so these tinciny wincy 28' boards just dont cut it for mine

Before i bought the Shaka I tried, Coreban, Naish, Starboard, DC, SupLove, Laird Coastrunner, Bark Expedition, Lahaui Kai (scary board

)
So as everyone says, try everything and narrow it down, its you that is paddling the thing and you have to be comfortable.
Good luck with it, and lets us know how you go.
BTW I started at 278 lbs and am now down to 255 lbs after 7 mths of paddling 3 times a week.
