I've fished interior lakes with chironomids alot, with many techniques, trolled even...I've always had the most success on the flyrod slowly retrieving them finger over finger, inching them in just a bit at a time. My favorite way to fish them is a slow sinking fly on either a sink tip or floating line with a really long leader and super light tippet. For me, anyways, its just so much more rewarding than trolling them...it feels like I'm more active in the whole experience. As for spinning rods, again its just one more degree of seperation from me and the fly (since i cant feel the line in my hand). I've never used a srtike indicator, i guess it just reminds me too much of a bobber. No real reason i dont like bobbers, maybe just the cheap red and white plastic! They look like little cartoon explosives or something. I'm no purist though, if mono worked better for me beleive me I'd do that!!!
