Hi Ed!
Back in KC several guys in the group that I hunted with regularly, had Pokes. They used them primarily for transport of decoys, and as a layout blind. Keep in mind they were using them in marshes like 4 Rivers or Maris Des Cygnes, where they needed something to get across the Borrow ditches, then something dry to lay in once to their site (once they crossed the barrow ditch they pulled the boat behind them while wading). For portablity they are great. They are tippy, and there isn't much room for gear. But if you need something to get to a remote marsh, transport a little gear across a short distance of deeper water (barrow ditch or something) they work great. In shin deep water, once decoys are deployed they are serviceable for a hunting platform, though cramped, tippy, and pretty pricey (for what they are) to my way of thinking.
All in all, I think they have limited applications for ducking. If you have the money to spend on a Kevlar Poke to pack in somewhere with little deep water and use it as a "shuttle / layout blind", it might not be a bad choice. For anything else, I think I would look at a MoMarsh or something.
Have a great day!
