Which Call do you use for

[Woodsman4God]

Hi Guys

I have a question about mouth calls and purring with them. Is it just preference or is there a particular type of call, single reed double reed etc that works better for purring. I have only been using them for about 3 years now. I have finally taught myself to purr on one and was just curious if particular types were easier or provide better sound for purrs. I realize the sound part is a little subjective to opinion. Any help from you guys would be appreciated
