I am using Lost River Game Calls. They are a new local company, but awesome. They make a grunt call that brought several whitetails within 20 yards of us while we were in Texas. Their turkey calls are great, too. They make mouth calls, slate calls, box calls, and have several different strikers to choose from. I haven't found anything from them that I haven't really liked. The website is www.lostrivergamecalls.com
They aren't in very many stores yet, but if you see something on the site that you like, let me know and I will get you any info you need.
