I bought the Kestral and Mantis. Still waiting on the mantis. I decided to try this route because of some neck and back surgeries. I cant carry the weight of a tree stand and my filming gear anymore. The Mantis weighs only 18oz. That sure beats 21lbs for my lone wolf climber. This past Sat I hunted bear for four hrs. out of the saddle while filming for a young buck from work. It was awesome. no discomfort whatsoever. .
