I use the Foiles method....I feel it is goosier and a lot faster.
Chris....Josh won the Champion of Champions at the Avery with the Sean Mann Eastern Shoreman (Birdseye Maple Flute), which is actually basically a short reed. Even Mann himself says it has the short reed guts, blows like a short reed with just a touch of flute, but still sounds like a flute. Josh Nuewiller has gotta have pin feathers! Another file on that site is of John Bolen, he is actually blowing the Foiles Meatcutter but since then John has gone back to the short reed for comps. John told me the main reason he blows a flute a lot is because "They sounds too much like a goose not to blow em"
There are still quite a bit of excellent callers still using flutes, e.i. McCree, McGown, etc.......Even Ritchie McNight says he prefers the sound of a flute over a SR, but SR's just have that speed and versatility
Another reason to switch it because calling all day from a layout blind can be very difficult with a flute, the doors come up to high and it is a really big hassle. Don't get me wrong.....I will pull out the Grounds Guides Best when I am hunting over water.
I myself am a short reed anthusiast. I love the crack they have, that short reed sound they have, the speed, the size, and the versitility. Plus they are sooo damn fun to call geese with!
