your flasher fly problem is probably due to the amount of line you are running between the dr ball and the flasher. salmon are not line shy i run 20 lb flea flicker to the swivel no leader for trout i use 12lb leaders 10 feet long. also your speed is a factor some days the magic number is 2.3 the next it could be 3.4 and it makes all the differance in the world. also try running nk28 instead of mags.
