COMMON SENSE!!!!!
Dont feel bad. I had the perfect poplar and set up and climbed. It was a fat, straight up with no limb kind of tree. I had my climber maxed out with pin adjustment and by the time I got to where I wanted to hunt, my platform had a 25 degree downward slope.
I need a solid mature tree I can barely wrap my hands around to strap. Its better off when you dont sway with the wind...I can only imagine a double ladder.
