Lightweight spinning reel with a clear bubble (float) and fly setup.
The bubble slides on the main line then add a swivel then leader/fly.
Fish the fly about 3’ behind the bubble with 4 lb clear leader.
#12 or so coachman, mosquito, Adams or muddler flies.
This set up lets you fish flies w/o getting tangled up in the brush or bottom debris and usually catches plenty of fish in the high lakes.
