Yes on the fluoro tippets! I've been going with heavier and heavier tippet strength over the past few years and haven't found the "ceiling" yet. 2x is now what I use for just about everything in lake fishing. No more breaking off fish and many fewer tangles in the leader. BTW - your two-tone nymph was killer this trip. I probably caught over 30 fish on one fly that was my point fly fished deep. I changed up to several other options for a bottom fly but the two-tone never went back in the box!
