I would say a good climber is more important than new arrows or a high quality bow because you certainly are going to have trouble shooting something when your climber falls down the tree and you are left dangling by your harness! It is all about safety for me because being a med student I got to see a couple bowhunters come into the E.R. I was working at who had fallen out of their climbers! (and they were dumb enough not to have harnesses on...[:-])
