Re: Casting questions from a rookie
Casting on a lawn, I've never been able to carry 100 feet of line before my presentation cast.
For me to cast 107' I would false cast about 58' on my last back cast, then I'd shoot about 7' of line.
The bottom line is: you have to experiment on you're own, but the more false casts you make the less line you'll probably be able to carry.
BTW, the lighter your fly line the more line you'll be able to carry, which is why many casters feel they cast farther with a DT line than with with a FT.
P.S In many casting tournaments, casters can pick up the line in front of them with the line lying in water. That way, with the increased water tension, they can carry more line (and execute only one back cast).
