You might want to check out the Togiak, it is a v shaped that kicks easy and is big so it will hold you fine. I have had mine about a year and a half and really like it. You sit high and it has plenty of pockets. I use it in the salt all the time and I think the V shape helps when punching through surf. I got mine for $119 through Cabelas and I think Sportmart has them for $139. If you search back to last summer on the saltwater board, you can check out photos of me, in the tube with a variety of flatties and seabass.
