I have paddled both boats, and now own a Burn. I haven't however done any overnighters in either of them yet.
The S Villain was comfortable, and was very good at staying on the surface, as well as being easy to boof. It got a little pushed around however in bigger water/reactionary waves. I am the same weight as you.
The new Burn design impressed me a lot. I had paddled the old style and never really cared for it. This boat will handle like its on rails, and do exactly what you want it to do with little hip movement, its really quite sporty! Where as the Villain had tendencies to drift a bit more.
Another thing I liked about the Burn is that it punches through breaking waves and holes without getting deflected much, which really lets the paddler be in control.
The Villain felt like you could put it on auto pilot and it did a lot of the work for you, it would be very stable, but somewhat get pinballed in higher volume runs, but I like to have a sportier, more active feel to my boats.
For your low volume overnighter, the Burn and the Villain will have plenty of room- the burn is going to be lighter, as the jackson creek boats have aluminum bulk head plates and tend to weigh about 5 lbs heavier already, without being loaded down. Both boats are fairly fast. So it really depends on your paddling style- if you want something that that is a little easier to boof, and stays on top of the water a little better, go with the jackson- if you like a sportier, more agile boat that pierces through the water better, I would say go for the Burn.
Just my thoughts, hope it helps a little.
