Starting off use a double reed. A triple reed requires a little more practice and will give you a raspier sound. I use both as most hunters do. Just experiment with different calls and see which ones are comfortable to you. The good thing is that mouth calls are not too expensive, so you can buy several and try them out. There are many brands out there, so just go shopping. I'm always buying different ones just to see how they sound. There is really no advantage from one over the other. They can both produce great sounds when used correctly. My advice is practice, practice, practice. Eventually you will use both in your arsenal.
