I think it depends what sort of playboat you want, or what sort of tricks you want to do. Corran's boats usually had good edges and carved really well, and were loose for spins and things.
Compare that to the better boats of today, say the new star series, since they won the last worlds. They won't carve as well as the riot/dragarossi boats. But they'll be better for the new loops style fancy tricks.
If you prefer to just surf holes, or carve around, or do cartwheels, the latest and greatest boats might not be the best. If you want to do the latest and greatest tricks, you should go for a boat that was made with the newer moves in mind. Something like the new stars or molan's. The new project x looks like it's added new volume but kept its rails...
Personally if I was you, since you already have an element which is made for carving, I would go for something on the other end of the scale.
If you narrow the choice of playboats down to 2-3 you seem to like, then you might get some help on which would suit you size wise the best.
