i don't know who this widgeonsflight guy is on here, but he makes alotta sense. Calls are specific to each person, my buddy and I both blow contests around north louisiana, we both blow acrylic, and not to brag, but we both sound dang good (contests to prove it), but no matter how hard i try, i can't blow his call worth anything. He's thesame way with my call, he sounds horrible with my call. They are both made by the same person, MR. Jeff with Klear Magic. BUt i know Mr. Robertson, i have seen him, met him, and heard him blow. He's a good guy, honest and christian as can be, but he ain't the greatest there is, was, or ever will be. He does hunt on private waters where there are few water locations other than the one he's on. that makes it easy to get them in there. but he's a nice guy and i'd be honored to have him in the blind with me. But the only way to find a call that fits you is to take a buddy with you to a hunting show or another forum where the duck call makers would gather and start blowing calls, acrylic, diff kinds of wood, polycarbonate, single reed, double reed, blow everything you can get your lips around. And let your buddy back up a bit and listen for you. The callsounds different ringing in your ear then it does at a distance. And don't spend alot of money on a call, you will lose it, the more expensive it is, the more likely you are to lose it.
