Yes,
The type/style does matter, Yes I do agree a decoy could be an old sock or buzzard feather blowing in the wind! to draw focus away or some silly teddy bear stuffed animal, in the majority of dense coyote populations, West of the Mississippi, as an example HOWEVER!
Depending on you geographical location and sesonal weather conditions when you can hunt when its prime fur season here in Maine and there is snow pack (4) feet deep in the backwoods and snow surface conditions change at times every couple hours, you are not going to stick no wire or cutout look alike in or on the ground, snow or no snow without some weather factor messing you up or freezing you up,your better off at times to use no decoy.
I am a firm beleiver in decoys, so to design and test a decoy/a look, an appearance that would work all around and with different motorized devises and geographical locations (I)we developed the "MONSTER MOUSE",Hec, we needed a name for our feather, teddy bear, ole sock or what have you and some guys and girls cant sew as in (Vaportrails Case)so I wanted to make it available to all predator hunters! Because, I truly do hunt and love this challenge, so I knew the decoy had to be able to stand up to the rain,snow,flatlands,mountains, and so on because it worked for us! One time we didn't even need a call!, We hooked the Monster Mouse on a fishing pole line and just reeled it in across a frozen lake that we had just crossed and a dang yote started chasing it, for awhile anyway, before I lifted him into next week with my RUGAR.
Anyway, In my opinion at least for us who enjoy living in the real Northeast and pursuing great northern yotes I'll always stand behind my Monster Mouse, and yes you to Vaportrail /ubbthreads/images/graemlins/grinning-smiley-003.gif
