I want to do it mostly for the purpose of long lining. Spending several hours per day leaning over the collective rather than away from it is just so much less painful on the back. It's also nicer for power line inspections. Just a lot smoother flying when you're crabbing along right side first (so you're lineman in the right seats can see better) versus left side first and fighting LTE the whole time. It also makes for some nice fast turns when slinging Xmas trees, I can move a lot faster spinning right hand turns rather than left turns.
