Yes Brummie, one most important aspect of fly fishing is that the size of the fish doesn't really matter, its the quality of the fish and whether it is "grown-on" or not.
And HOW the fish was caught.
Some of the most enjoyable trout fishing I ever experienced was in a tiny stream which cascaded down from the Eastern Cape Drakensberg. It was full of wild browns up to 2 lbs. And I can tell you that to hook a brown of this size in such a stream on a 4 or 5 weight outfit is twice as exciting as hooking a 20lb Trevally in the surf.
