I have used ladder staging and pump jacks, but never felt very secure. I have now gone to metal box staging. While it is probably the most expensive option, it is very secure. I am not a contractor but have 2 houses, a camp and barn to maintain. I have eight "lifts" and some extra cross bracing. I have a little less than $1500 invested, but figure that if I avoid one trip to the emergency room, I'm way ahead.
The staging I have is 5' x 7' and 6'4" tall. Half of each end has metal ladder rungs for climbing. If you put the ladder side towards the building, you can put the staging planks at just the right height for the work you are doing.
If you have only the one project, metal staging can also be rented. When I checked about 10 years ago, it was $6 a lift, for a month. I'm sure it's gone up since.
Hope this info is helpful,
Paul
