Using a screwdriver as a downhaul tool is not advisable... if you slip, you could end up with some nasty injuries.
Use whatever you can get your hands on, I reckon!!!

I used an umbrella handle a while back, borrowed off the missus and rugrats that were my audience for the day.....(they got a little wet....but saved me the 50m walk to the car to get my pulla!!!)
