not easy trying to get both hands doing diffrent things at the same time, dont know how much fly casting you have done but one thing that helped me was to stand at a slight angle to the direction i was casting so with a slight turn of my head i could see the fly on the back cast. it helped impove my timing and balance , also rock back and forth slightly with your cast to help get into a rythm,.it got drummed into me to dance with the cast ( rock back n forth,), proberly to the amusement of freind that taught me ...... a big thanks to him .
