I have used just about all of them and for the most part there isn't a lot of difference just for the thrift of it try out one of the discount brands I see Olympic around for $10 to $15 at discount stores ie Swains. I have several in DT and WF they are fine and probably made by Cortland or SA so in this case you might just get what you pay for at a cheaper cost.
Always struck me as odd that people would bust there ass to save a couple of bucks on rods and then fork over top dollar for a fly line that is no better than one that cost 75% less.
