I had two custom calls made from Gooserbat, both three read Ghost cuts, lightly stretched, both stacked with natural latex, one with a grey top read and one with a latex top read.
Aside from sounding great, the calls feel extremely durable compared to the mass produced ones I've been buying.
I also found the custom call page very helpful as it lays out the differences between latex/stretch/cuts.
Hopefully someone finds this helpful!
Glad you are liking those.
