@Grasshopper 22 , great question that I had this past season. I found that having myself positioned in the tree with cover between myself and the likely avenue of approach was the greater of the two problems you identified. Using the WEI ROS, I found that with minimal practice and significant failures, I could gain nearly full 360 degree shooting without losing much of the range of motion and being able to get my "strong side". I am adding the WEI Perch this year to get some better ankle/arch relief and add some more confidence in rotating around to the weak/blind 6 o'clock shot.
The biggest thing that I learned (through some hard lessons) was how to transition around the ROS with my bow in hand and not fighting my tether/bridge. I practiced plenty with getting the steps set up, get my workspace dialed in and drawing from my strong side, but didn't plan on any of the off-hand/rotation shots. I missed three opportunities fumbling around with my rig trying to get to my strong side. I could have practiced those transition techniques even a few times and I would have increased my probability of getting a shot off. One instance of a hard lesson was following a fast-moving ninny (antlerless area + bonus tag) from my strong side around to the 9 o'clock (around the tree the wrong way) who wouldn't stop. As I progressed around my ROS at full draw, I found myself nearly choked out by my tether. I ended up like the ball at the end of a pendulum arcing back around the tree after slipping off my step. Needless to say, I never recovered that arrow. Lodged in the top canopy of a late-season elm and fortunately not my foot.
Take the time this summer to actually haul the bow up. Set cones up in a simulated scene of where you think the avenues of approach are and then work on the transition techniques until they are fluid. Kind of like watching
@g2outdoors or some of these other skilled guys work around a tree.
