Re: I need more distance
It sounds to me that you've got plenty of rod to accomplish your goal. You could spend more money if you want on your gear, but it still comes down to learning to double-haul and then practice, practice, and more practice.
Earlier today, I took five different 7.5' fly rods into my backyard to practice. Even with a gusty wind knocking the forward cast back and preventing me from casting full distance, each rod capably cast +75'. Oh, and did I say the rods were all vintage fiberglass. Also, the rod that cast the furthest (+90')cost me less than $30, brand new, over the winter.
How I was able to accomplish this? Practice, practice, and more practice.
