Hi all. I am heading out for a weekend of nymphing and wanted to try a dropper rig for the first time. Just wanted to see what everyone thought on the most productive approach, IE 2 or 3 flies and should I use different sizes of the same pattern or say run a pheasant tail and a hare's ear. I'll be fishing in a medium size mountain stream, rainbows, brown, brook etc. Also, am I better to use a splitshot above flies or at the end of my tippet under the flies? LOL probably gonna get alot of different views on this, but that's kinda what I'm looking for.

Thanks,
Steve
