All of these tips are good ones. I have always waited to tie off unless things felt a bit scary. I have a summit razor and have always felt pretty safe on the way up with the bar around or under my bum at tall times. I would say you would most likely be better of just taking that long way around and tie off from the get go.

1. Tie off
2. Pull up rope
3. Attach you climber together at all time while climbing
