Re: Length of Cast
Generally, the length of your cast is determined by the amount of line you have out of the tip of the rod, so if you were practicing you could mark your line in ten foot increments with a sharpy and know just how much "line" you can cast. For the purposes of just how far have you cast, the rod length must be taken into account also.
So, kinda both...if you have an 8 1/2 foot rod and can cast with accuracy to 30 feet, you are probably casting about 21.5 feet of fly line.
Hope this helps,
