I just got a primos high roller whistle, and it is the only call i have found that will put that "flutter" into your whistle without using voice. it really sounds neat and swampy. And yeah, Walmart is a great place to get duck calls near the end of the season, they about give em away. Calls that you would pay 30$ for on opening day go for 5-8$, 20$ calls even less. it is a great way to pick up and try alot of calls and be able to practice with them in the offseason, having a whole year to get used to them. Walmart is where ive picked up most of my 20+ call collection. I have actually given away about 10 calls that I didnt care for, just cuz they were so cheap. The duck commander whistle sounds good, but you need alot of air to make it sound right and it is bulky. Looks like a can of tomato soup hangin on your lanyard.
