that roll cast is a must have in tight spots: the above is right on about practicing short

get out on the lawn with either no fly or the hook cut but still using a leader

I am pretty wristy with this (not sure if that is the standard way or not)

start with just the motion then with targets then take a couple steps back and repeat both parts until you can move enough line to get the job done where you want to fish. don't worry about going a mile with this like you might see a pro doing: I rarely have to roll that far as most of the time if you need to roll its because the spots are tight
