Not sure about the 16' but I paddle a Legend 15 in RX on the narrow streams in the Ozarks. I can tell you from my experience keeping it on moving water is important.
When I'm in between riffles or on a lake, the paddling experience quickly declines. Add a little wind in there and I'm spending more time doing corrective strokes than fishing.
I know the rocker is 2.5" so it's intended more for moving water, and I'm willing to sacrifice those times where I'm in the dead water for the way it handles in the moving water.
It's been beat up pretty good, but the RX seems to take the rocks and logs pretty well after 2 years. It's light and has plenty of storage for me on overnight trips ( I paddle it solo exclusively)
Like I said, don;t know much about the 16' but can't imagine they are entirely different.....
