Fellow bowhunters!

I am looking for some feedback and ideas on my new style grunt tube.
I totally understand that 97% of you used production style grunt calls, but would like your input on my handmade ones. What do you look for a grunt call? Style? Feel? Looks? These calls are adjustable from a deeper sound, to a softer doe grunt/bleat.
Again, feedback and thoughts!
