Have had the HS flute, reed owl, K&H reed owl, Cane creek reed owl, an old Camp callers reeded flute (huge call but very nice), the original palmers hoot tube.
Now I have a boogeyman owl. Still like natural voice better than anything. Funny back in the late 80s and early 90s they would gobble at an owl call like crazy. Cannot hardly get em to now. BUT it fires the owls up and they gobble at the real owls now.
A canada goose call........90% of the time it works every time lol. They like a wood duck call too.
