I'm 230 pies and I would recommend that you check out the Mako King and the Litewave Wing. Those are both great boards, though the Wing is definitely aimed at light wind/heavy riders. The Mako King 165 will ride smaller than its size indicates, closer to a 155 or so. Its narrowed, rounded tips, rocker and aggressive concave add up to a board that will slice through chop like it's not even there, easy on the knees, and possible to hold an incredible amount of power. Which also happens to make it amazing for jumping. It's very stiff, so if you're someone that relies on board flex (pop) instead of technique to get you off the water when you jump, you'll have to learn to do that. Otherwise, I love jumping Makos. One of my friends likes to say that the Mako King is "like a Cadillac for your feet" and I'm inclined to agree. One note here: If you're unhooking and throwing handlepasses all day, the Mako is NOT the board for you.
The Litewave Wing (whether 155 or 165) is a lightwind board that doesn't know it. Decent rocker, concave, and parabolic sidecuts make that board both able and fun to ride in a variety of conditions, from flat to waves. The Kick-S 144 would be pretty good as well. It also has some rocker and concave on the bottom that make it a chop killer, while being wide enough to help keep it from being power hungry.
All that said, understand that the more rocker a board has, the more power it'll take to ride it. So if your current board is 145x45 and flat, if you get something that's not flat and has some rocker, you're likely going to need something bigger than the sizes you're talking about. If you go with the Misfit, the bigger size is your best option, but likely isn't going to be quite big enough, IMHO.
I'd recommend the Mako King for you, as it's just so versatile and fun to ride. Most people don't understand how hard it is for guys our size (and thank you for making me feel slightly smaller
) to ride without large enough boards. Good luck to you and let us know how you end up!
*Disclaimer-I sell and ride all of the aforementioned boards (plus many more)
