Bryan, if it's for rivers then have a look at the Partridge Dry & Delicate line. My friend swears by them and it's all he ever uses now.
Also, there's a guy on eBay selling "Redditch" fly lines. I've got a couple of these and they seem superb, although I haven't fish with them yet. They are only ?4.99 with free postage so you've not lost anything. The story goes that he was the night supervisor at Shakespeare and got the sack after years of "One for you, one for me" off the production line. He's now set up his own plant and can copy any line that Shakespeare bring out as he knows how they manufacture them.
See what you think and let us know.
Also, if you're going to the Fish In I'll have mine there so you can have a swish and cast to see what you think (if that's not too long to wait).
