Hey Ibupnort – I spent the money on the 5600 deluxe last year. I will start with a couple of the cons.
1) it is a bigger shack if you only plan on fishing by yourself. (could also be a pro ) 2) If your boots have a lot of snow or ice build up the floor can be a little slick. 3) One day the wind was blowing really hard and I took it out by myself. It was hard to set up, because there wasn’t any snow to pack around it and I didn’t have any ice anchors. I ended up just taking it down. (I am guessing this would be a problem for a lot of the shacks, seeing as the wind was really strong that day)
Pros
1) It is a bigger shack, plenty of room. (I fished three out of mine last year.) 2) The material is great, feels very strong, unlike some of the other ones I have seen. 3) folder easily into the back of my SUV.
If you plan on fishing with a partner a lot of definitely recommend them. As of right now I am looking for a used 1-man for certain occasions when I don’t need all the room.
Any other questions just let me know.
