Biggie,are you a weldor? If you are I build a ladder stand you should see. They lean against the tree at the angle of a regular ladder,very stable,and with a swivel seat,quick to build and so solid I don`t even tie to the tree anymore unless the ground is uneven. I`ve not built one over 13ft.,so might not be tall enough for you though.Every time someone hunts in one I can`t get it back,they just wont give it up. I`ve never sold one but have traded them for hunts,bows,and bribes. If you want to see it I can take a picture and post tomorrow. bob
