Hi...echoing what most everyone has said, just do your best to demo and try out the boats you are considering. This is especially important, as a big guy...take it from me as I'm 290+! Yeah, some shops have a pool, like the place over in Dallas or up in Dawsonville. While the pool doesn't give you much room to paddle around, you can at least get a good feel for stability and how much water may come up into the boat through the scuppers. You may be able to get a quick demo of a boat on the water as well, depending on the shop. I was able to try out a few boats this way a few months back. Good luck!
