Each of the three reeds in the Wicked Sister were carefully selected to achieve turkey calling perfection. The slightly thicker top latex reed with W-cut covers two slightly thinner .003"" latex reeds. A small notch on the middle reed adds just the right amount of rasp. It's got just the backbone for cutts and cackles and deep raspy yelps. W-cut triple reed Notched middle reed for extra rasp Easy to use
