right handed, platform , and compound bow. im pretty positive that im over thinking all this so im going to go play around in the off season to get things figured out
Right handed shooters do best setting up shooting for expected shots to the strong side (your left side).11 o'clock to 7 o'clock with 9 o'clock as the ideal. Most new guys can shoot better off a platform than a ROS, and tend to be more comfortable on the platform.
Weak side shots are more difficult but its generally harder for us trad guys because we tend to short draw on the weak side. Low tether is easier to cross over but it shortens free tether and limits travel around the tree.
Something that you will want to practice is getting your bow over the brigde/tether for the weak side.
The tree itself...
Huge trees are more difficult to climb and limit your "travel" around the tree, but they do conceal your silhouette better than a tiny tree. Small trees are easy to climb and its easier to get around to shoot 12 or 1 o'clock, but its harder to hide in small trees.
I like trees with cover. Multi trunk,or species that hold leaves longer...beech or white oaks have that trait in my area.
