Here is the link
to a bunch of really good videos I gathered for an article I did on running line management. They are all very good but pay attention to the one by Nate Bailey.
Berkley sinks so for long casts sometimes it helps to at least hold a couple big coils unless you are in moving water in which case you might need to divide your running line by three, at least if you double spey. Sometimes you can get away with holding them all in one finger.
Here is a cut in paste from the article.
Rule #1 Always stretch your mono running line but never across your yard at adamís apple level during high traffic hours for foot travel. Wives do not appreciate this. A better option on the river is to wear rubber gloves and stretch it by hand before you fish.
#2 Donít count when stripping line if you donít have too. Thatís too much like a work activity. Strip it in until it looks about right.
#3 Itís almost impossible not to count.
#4 Use Varivas running line so you donít have to count, just strip it in and let it fly, at least if your in slack water. Varivas Airs running line is expensive but each spool is labeled ďNo counting required!Ē
#5 For poor people Berkley Big Game #40 works pretty good for running line although it does tend to sink. But itís cheap and when it gets too curly you just chop it off, stash it in your waders and pull more fresh stuff off the spool, loop it, and go back to fishing.
#6 With mono running line I grip the line with my top hand birdy finger, run it over the reel and grip it with my bottom hand birdy finger, in the fold of skin on the top joint, always, then I release both birdy fingers for the cast, similar to Robert Gillespieís video below, only I use as big of loops as I can get away with, including non at all.
#7 25 lbs test Berkley works really good, but sometimes it will break and you may have to go for a swim to retrieve that expensive shooting head you just bought. So only use at least #40 and replace it if it gets dinged on the stones.
#8 You can also hold your coils in your top thumb. Press the loops with your thumb onto the cork and release the thumb when you cast. If you are transitioning from the double birdie finger mono release be careful not to throw your rod into the river.
