Start the back cast a little low then, without pausing on the backcast, bring the rod tip up and over in one smooth motion. I've found it works well with 4/5 weight moderate action rods and big hoppers and weighted buggers.
I have a picture in my mind of a somewhat tight but slightly lopsided U shaped casting motion. Am I on the right channel ?
