I have both. When I hunt with the kestrel I use the tethrd recliner. It’s the hook up that’s better but how small it is to store is great too. I’ve broke a few of the s hooks on the aero back band. Not leaning against it but when taking weight off to adjust tether and other things. If the back band drops down and you sit into the saddle I usually wind up sitting on the back band. The tethrd backband isn’t comfortable if you sit on it but it will hold your weight. It also folds up and goes into my sys hauler under the tether.
