Next Board

Right now I have a 6'10 fun shape, and now that the fall and winter seasons are upon us I'm looking into a board that can handle the bigger waves and that is more responsive and will turn better. The dimensions on my current board are 6'10 x 21 1/2 x 2 3/4. I;m not really sure what to get paddling difficulty isnt really that much of a problem. Thanks for your help
