@fryfly didn't see your last questions when I just replied
yes & yes. wind is never fun but my double hauling technique is OK and I can launch a 6" wind resistant fly a measured 27m on a #9 pike taper full floating line. people might think it's a bit wimpy, but sometimes I choose to wear a wristband for casting the #9 all day with big flies because I have a previous (unrelated) shoulder injury which needed reconstructive surgery and this relieves the pressure on it.
if it happens, it will be Dec-March in the Southern hemisphere.
my budget is flexible except that my business has brought almost no money in for 2 years and I'm living very cheaply on savings at the moment - so think of it as a very tight but slightly elastic constraint
my main problem is that I read Lefty Kreh's book on Saltwater Flyfishing a few years ago and have since become slightly obsessed with the possibility of some of my favourite things >> big beautiful fish that pull hard - fly fishing - tropical surroundings & warm water << all converging in one activity. Have done some on my own in Brazil catching what they call Robalo (Snook in the US) and it was fantastic fun on an #8 and #9 so now I want MORE.
I will be going to a part of Brazil that is probably completely unexplored for fly fishing. A local big game captain has given me evidence of big Tarpon in the area and told me that "no one knows how to catch them". Except that is for an old guy with a hand line that was pulled out of his dugout canoe and then towed around for 2 hours recently by one that turned out to be 79kg or about 173lb in old money. And lure fishermen that occasionally feel a very strong jerk, see something enormous jump out of the water and then retrieve what is left of their plug.
I am planning boat fishing more, but money will again be a constraint. Hoping to rent a place there for a couple of months and get to know the area, perhaps some wading or even hire a rowing boat for more sheltered areas. Honest answer is I don't know until I get there.
