Wow! So much good advice I can’t respond to all of it. First to answer a few questions:
I am hunting in a tree stand above where 3 major trails converge. I am shooting at 55# right now. I’m not strained pulling it back or staying on target. I can easily keep my draw for 30 seconds. I practice regularly from a ladder stand I have set up at my house. I really like the idea of having one “bad arrow” to shoot into the dirt at the end of each sit to see where I’m at and just practice shooting cold.
