I got a two man Summit a couple seasons ago, nice and stable (of course installation is a key component to the rigidity of the system)
Pros: comfortable, spacious, feels safer
Cons: less mobility, heavy (3 person installation)
If you have a private chunk for whitetail it can be a game changer!
Note: if you archery hunt, raise shooting rail. Had a 5x5 WT walk under my stand at 3 yards but couldn’t lower my bow! If my son isn’t hunting with me, the extra seat holds my gear for a long sit.
