Any kayakers out there?

Im looking at getting a kayak. I'm 5'11", 190 lbs relatively in good shape. My wish list is basic:
Needs to have enough storage for a 4-5 day trip
Needs to be light enough to portage 1-2 km without crazy hours working out 6months before. I'm thinking 50 lbs-ish. I'll probably end up getting a cart, but they aren't always practical in rough terrain.
Needs to be stable enough in ocean swells, I love paddling out in the Broken Group.

My first go to was the Seaward Tyee. I can't find any used. And with the new tank upgrade they're a bit pricey to buy new for my budget right now.
Next up was Current Designs Gulfstream. Found one in Vic and I'm headed there tomorrow to take a look at it.
There's also a Current Designs Slipstream, but I think it's going to be too tight. Seems to be more fitted for smaller type people.
Any thoughts from those in the know?
