That depends entirely on the situation. If its a big field on a windy day, I love the Zinks SR-1, but its pricey for Saturday fair weather hunters.

On the water, where sound carries better... that call can be too loud... and I have a Sean Mann Eastern Shoreman Flute (the poly carb express.... $60) thats very easy to use... and slam full of goose.... most folks have trouble blowing flutes these days... but if you think "T's" instead of "Ws'" its not that hard.
