Summit IMO is the most comfortable, safe and secure climbing stand line bar none. I have used them since the Sabre days and won't trust my life and hunting enjoyment to another brand.
I own a Cobra XLS and a Goliath top to go with my climbing platform and they will do anything I want them to gun or bow. Don't overlook their fixed stand stuff either! Bucksteps, climbing sticks , ladders and stands. Same quality and ease of use.

Great stands and great people running the company.
