For you a 111 is a sinker. The next step could be a 9.0-9.5 rig + iSonic133 for example (or a formula, or a longboard if that is of interest to you). In lighter winds you'll need some flotation, slogging, etc.
And as you've said, lose some weight ;-)
Edit: with regard to wave board, I think it would be much better for you to look for freestylewave, or crossover board for strong wind days (such as Kombat, jp fsw, etc). Unless you're going to ride waves of course.
