When you go around in the summer (or spring) and test climber trees, take a notepad and write down which "settings" you use for each tree. Most all climbers have settings (ie tree width) and I have found if you write them down, and create a sheet with info for each tree, you make life easier when you get to the tree.

Example info for each tree:

Winds:S,SW,W ( I will be using Greg H's tactic of wind degrees this year)
Settings: Top-4 hole Bottom-2nd hole
