Fly size vs. Rod wt.
Being a newbie to fly fishing I ask this question. I've learned that too large a fly and too light a rod means you cant turn it over and cast it very well. That being said, can you every have too much rod for too small a fly? Like for instance an 8wt rod with a tiny 18 size fly. Or is it just a matter of matching down your leader to an appropriately sized tippet or smaller mono?
