I asked for some advice on fly lines a while back here on the site and several folks suggested the Rio Lines for various applications. I ended up buying the Rio Grand WF for my 6 weight and love it. It really shoots line well and has minimal memory. It loads very well. I also bought the Selective Trout II in DT for a 4 weight bamboo rod. It has just about no memory what so ever, lays a fly down very nicely, and will still reach out there if necessary. I fished both very hard this summer here in Alaska and they are working very well. Great fly lines......and a sponsor, eh? I would buy them again in a heartbeat.
