"With a short line I'm only lifting the rod to my ear and not breaking my wrist,"
You'll have to excuse me being boringly pedantic . . . as an instructor, being able to demonstrate it is a key feature of our qualification.
A casting stroke should start with the rod tip as close to the water level as possible, usually in a boat, I find I articulate my wrist down towards the water - more comfortable than leaning forward and pointing the rod at the water with a rigid arm. Bringing the rod hand to the ear straightens the wrist - slow start, rapid finish?
Interesting that you wiggle line out of the rod tip from a drifting boat - do you not find that the drifting boat tends to overtake your 'wiggle' in anything other than the gentlest of breezes?
". . . then roll it out in front then straight into a back cast, what I do during that I can't say myself, it's a multiple of movements I can't describe but I'm sure your familiar with."
Pretty sure there'll be a bit of 'wrist role play in there.
