I never had a kproblem with my Baker stand, but then I never ever stood on anything but the outside third either. We made some crotch stands, the first version was like flying an experimental stunt plane. They would flip you upside down in a heart beat. The second version worked and they all got stolen out of the trees. The problem that I had was that I worked on very tall buildings in those days, 18 feet seemed like jumping distance to me.
The closest I came to dieing was with a Sabor climbing stand, "the widow maker" as my son called it. After two hours of hanging, I shifted my weight on the seat and it dumped me off. The waist/chest strap nearly killed me.
I now only use the best tree stand I have ever used, a Huntmore chair, plenty high enough off the ground for me these days.
