This trip is on my "Top Ten Trips of My Lifetime" list.
There is only one outfitter, River Plate Outfitters, I would recommend because they can move their floating camp up or down
stream to stay in the best water conditions for fly fishing. Liveaboards draft too much water depth so they are limited to deeper water.
Land based lodges can't move with the extreme water levels so they can be too low or too high for good fly fishing.
Captain Andy Guibord at Kiene's Fly Shop has been on this amazing trip with groups of our customers.
We use high end 9 weight fly rods because they are very light for casting all day long and fighting powerful fish.
Sage and Orvis seem to be the most popular great casting and very light weight too.
We used #9 Rio "Outbound Short Tropical" floating fly lines.
Very simple, very heavy leaders are need and this is the only trip you have to have a stripping glove for.
We found that the #2/0 Umpqua Airhead fly in Yellow/Red was great for us.
My largest is 17# and my cousin Steve got one 19#.
Regulars like Jerry Lyerly and Jim Christianson have landed several over 20#.
Any Peacock over 15# is a fight of your lifetime.
We were helped by our good friends at the Reno Fly Shop getting setup for our first trip to Brazil.
