You are going to One of the places in the world with a wide selection of some of the finest whiskey distilleries and you are worried about fishing?
I would advise that you sample their most famous product when and wherever the opportunity arises and the fishing will take care of itself. The people you'd most want to fish with will in all probability be found in those facilities or at the least known to the people in those facilities.
The distilleries are easy to suss out and chart, and I have some favorites lined up. Don't need word of mouth recommendations on those, I know what I like. Fishing guides are a different story, word of mouth recommendations are worth their weight in gold.
Thanks for the suggestion Pugs, I will check that out.
