I'm 6'3'' 200 lbs, size 13 foot, 36 inseam too.
I love mine!
Plenty of room, the knees are up more then they were outward, I'm still very comfortable in mine. It feels faster, easier to caught waves on the fly, edgier on the surf for cutting back and forth. Just as easier, if not easier to do bow and stern stalls in flat water. I can get cartwheels in shallow holes that I couldn't in the past because of the shorter ends on the boat.
Problems/dislikes, the footbag moves around a lot on me, i thing I'm going to glue some foam on the sides of the bag to help create walls to hold it in place. The other problem I've found, because its a shorter boat, when I paddle forward with speed the nose dives, or just can't keep water from splashing over the bow, and I have to fight hard to keep the bow up.
If you love to playboat, then you're in for a treat. I think you'll love the upgrades. If you are a little more on the river running side, I would stay in your present boat.
