I know that alot of guys shoot pins and then tell themselves to "hold a little low " when up in the tree but when it comes time to drop the string , the only thing I want to be thinking about is that exit hole on the opposite front leg. I had enough of poor shots and total misses on deer to know fixed pins were not for me up in a tree. Unacceptible to me.

Regarding the up/down hill compensation , my keller locks into a fixed position for ground shooting so then I would say I was in the same boat with the fixed pin shooters. I know that you can shoot strait up in a tree with the pendulum and be accurate as I have taken raccoons that way.

If I have a choice to be dead on without thinking about it or to be just slightly off but have to think and compensate , I know what I will and have chosen. To each his own as they say.
