interesting! i think you will have to be prepared to lose lots of flies to these buggers, since they really fight dirty, (wrap themselves around anything submerged) , read about it in micheal solomon's book "Varswater hengel in SA". Its an old book, but has some good info and tips. He discribes how to catch them on bait though.
Will get it when im at home again, and see what info i can post here for you guys.
Cheers
