Have graduated from just floating lines to sink tip and sinking lines. Had good luck with sinking line at Pass Lake with a green bugger. Are sink tips just for "surface" wet fly fishing and sinking just for getting deep? What about chronomids? Looked like everyone was using sink tips and sitting there. Fished Coldwater Lake by St. Helens last summer and hooked a couple fish with egg/leech with a sink tip, should I be going deep with a full sink? On rivers, sink tip with a wet fly, floating with a dry? I know there's probably a million combinations but any rules of thumb. I've read the books but want to hear from the "experts"
