I'm also a kayak hammock-camper.
The Clarks are money well-spent. Period.
Weight isn't as big an issue, since the boat is hauling it (compared to long-distance backpacking). Luxury and durability is what you'll get with the Clark.
I have owned a North American model (camo), and now own a camo NX-250 model. The 250 is the only way to fly!
I'd get the 250 with Vertex tarp, or an aftermarket tarp in the 10X10 or 12X12 foot range. I personally don't care for Clark's standard and XL tarps.
Yesterday's tomorrow is tomorrow's yesterday. It's the only day that counts.
