Kelly Gallop had a great informative presentation at the Expo. Learned a few things that I plan to practice. As what others have said, the sink tip is great on the Bow. I am due to pick up a new one in the near future. I fish streamers, often double rigs when in the pontoon, with a 7 wt. sage VPS and a SA wt tip express. It is a 15 foot head. I am going 25 next time for some of the reasons Russ had mentioned. I only use 12-18" leader, staight 10 or 12 lb. Maxima. Longer leaders defeat the purpose of the sink tip and you get a belly in the line with your fly up and not in the hot zone. IMO
I think I read in a McLennan book that when Lefty Kreh fished the Bow he only used a 10-12" leader.
I also like the advice on unweighted streamers. I tie all my own flies and have in the past weighted to heavy. Gets it down all right but sometimes to much makes it act unnatural. I now tie with a variety of weights.
You will like the streamers and sink tip when the Bow is completing run off. Big browns on the banks!!!!!!!!!!!!
