I'm using the Buck Gardner Grey Ghost acrylic call. Bought it 3 weeks ago at Cabela's in Saskatoon for $59.99. Sounds and works great. Took little effort to get it figured out and it is very easy to work. I also bought a Buck Gardner Speculator, Specklebelly call at the same time, was on sale for $49.99, looks identical to the Grey Ghost but black instead of white and it has been easy to figure out as well. We have been pulling both snows and specks right down into the decoys for under 20 yard shots and only run 3 full body snows mixed into our Canada's so I would say based on past experiences the calls are helping greatly. Hard to go wrong with a nice Acrylic call for under $60!
