I have buddies using echo calls and like them and some even have some Duck Commander calls. I can not stand toxic calls at all. My buddy was a staffer for them for one year and gave me a couple to try. They sounded terrible.
RNT DC Mondo is my go to single reed. Takes a decent amount of air to work this call but has a nice rasp to it. Sounds like an old pissed off hen. Lynch Mob Jezebel is another great call. Its a double reed out of the box but can be run as a single reed with a little work. Sounds super ducky. A perfect call for hails and bouncing hens.
