I have both types of stands and primarily use the lock-on type because of the versatility. I really wanted an Ol' Man climber for years ( I got started a long time ago with one of the old Baker climbers). However, after I finally broke down and bought one, I found that it actually takes me longer to get set up in it than it does to screw-in steps and position my fixed position stand. I like using large tree with lots of limbs for cover -- can't do that with my climber. And, as for safety . . . I have taken a fairly rapid descent in my climber and have had friends do the same. The fixed position stands have yet to fail me.
