] There are few things more fun in fly fishing than catching bluegills with a popper or nymph.  For the most part, once you find them it's easy and un-challenging fishing.  But if you want to up your game and chase trophy bluegills, the kind that will put a big bend in a 3-weight rod, you need special techniques.  This week Orvis-endorsed guide Kip Vieth shares his passion for big bluegills, and his special techniques for catching them--even in summer heat. In the Fly Box this week, we answer the following questions from listeners: I had a big brown trout chase my fly right after a big tumble of branches rolled down the river on top of him.  Is this common? What can I do with some grouse feathers I obtained? Does a 7 1/2-foot knotless leader have the same level tippet length as a 9or 12-footer, or is the tippet length proportional? I started tying my own leaders but had a blood knot break.  Should I go back to knotless leaders? Would it be a good idea to tie smaller streamers with a shank and a trailing stinger as opposed to using a longer-shank hook? I have heard that long-shank hooks don't hold fish as well. What are some good rules for keeping your distance on crowded trout streams? I always hook my fly onto one of my guides but recently I had a guide break when I was pulling the rod apart.  Is that a bad practice and am I weakening the guides by doing this? When someone says they are fishing a 9-foot or 12-foot leader, does that length include the tippet? I had a Davey Knot break on heavy tippet.  Is the Davey Knot weaker in heavier materials? How do I keep the fly line from pulling my leader back inside the guides when making short casts?
