When you set your deck you need to find the perfect compramise between ease of standing from a sitting position and stand clearance while standing. I' ve found a slight angle in my knees while sitting provides this. I can stand with only one arms help, and it provides some bow clearance. I' m taking 3-4" off my bow this year (new bow) to provide for more clearance.
I also would like the deer to show up on my left, but that doesn' t always happen. 23' has been my mainstay height for some time now.
Good luck.
