Definately paddle both and then decide. I found in the short time of yak ownership that the whole idea of buying the widest yak you can get for stability reasons soon looses is appeal after you have it a while. The big wide yaks become like tanks in the water and you'll find yourself working harder to get anywhere. As you gain experience and skills on the water, you'll most likely start wishing for a faster more streamline boat.
The FnD is an excellent kayak. I have paddle them quite a bit. have a friend that first introduced me to yak fishing about 7 years ago and let me borrow his FnD off and on. Personally, I would go with a boat with a 29"-31" beam. My LiquidLogic has a 31" beam. I'm certainly not a small guy with that pooch of mine. I don't try to stand on mine, but I can easily swing my legs over the side and fish that way or access my gear easy enough in the rear tank well.
Don't buy without trying. Good luck. Whatever you decide on, you'll love it once you try it.
