Thanks everyone.
I sat the saddle for the first time today! I started at ground level and then I sat at 15 or so feet. I tried leaning and sitting, swinging around the tree and standing on the platform with my back against the tree to simulate weak-side bow aiming. And I also took a short walk of 3/4 of a mile with the saddle on.
It's going to be a long learning process but I loved how light the whole setup was and the mobility I had. It also felt very safe (I am afraid of heights and climbing a tree has always been a challenge)
Next step is to start shooting from the saddle and reading Hamlet on it to test if I can stay on the saddle long enough LOL.
Thanks everyone and I look forward to asking meaningful questions and sharing my experience.
