Just ordered what may prove my last call purchase. (Actually sent a hedge Microhen insert to RNT for fitting with an ivory Old Style barrel that may arrive here later, but it's been there a while.) May have finally gotten over a decades long case of magic flute syndrome and feel like I've got about all of my calling bases covered as well as can be. With the lone exception being the whistling tree ducks: black-bellied and fulvous. Already have something they eat up, but it lacks the volume to reach out and pull them any real distance.
To that end, I've been fooling with a plastic Acme herding dog whistle that's loud and closer to the correct tones than whistles made for other whistling species - and, more to the point, has shown real promise on game. But it's tone is too, well, plastic-like to suit me, so I've ordered a stainless steel Montana Lite I hope to get spot on with. (Ironically, one apparently has to go through a shop in Great Brittan to buy a whistle made in Montana.)
If the dang thing does what I think it will, I may just have to find something else to obsess over. I'll be lost.
