I am here.
Hard Feed chuckle. hmmm I haven't given it much thought.
I don't think they run as fast as a single reed comp/open water type call. But I know I do it on my DT and have not noticed it being to tough. Mostly I just single cut with most of my hunting calls.
I am at work right now and don't have any calls with me to test it out, but when I get home I will run a double cut feed, and a single cut. on three calls and compare them on "how easy or tough they are" I will use a Zinc XR-2, A rowdy DOA double trouble ( I will run one as a double then one as a single), and a RNT shortbarrel ( I could do the short barrel as a double and single as well). This will still only offer a comparison for how I feed, and still be open to opinion to some extent.
I could record it if you want? I guess.
I will post results tomorrow. I am going fishin' tonight.
