I HAVE HAD GREAT SUCCESS WITH THE MAD SUPER ALUMINATOR, AND THE H S STRUT TRIPLE GLASS. THE ALUM. WORKS WHEN IT' S WET WITH THE CARBON STRIKER. GREAT FOR RAINY DAYS. VERY VERSATILE, LOUD OR SOFT CALLING. THE TRIPLE GLASS IS BETTER FOR THE SOFT PURRS AND CLUCKS BUT IS ALSO GOOD FOR LOUD CUTTING. I NORMALLY CARRY BOTH JUST IN CASE THEY DON' T ANSWER ONE OF THEM.
IT SOUNDS LIKE THERE ARE A LOT OF GOOD SLATE CALLS OUT THERE. IT' S JUST A MATTER OF PERSONAL PREFERENCE (BOTH THE HUNTER AND THE BIRDS).
