the video was just one big advertisement for primos and the predator surpreme... in my opinion. It didnt seem to give enough information on how to set up and what tactics to use. But, primos does make some pretty good calls. I have their "still" cottontail w/ the vinyl reed, and it is just about one of the best closed reed calls I have heard for calling bobcats, simply because the sound can be lowered to a whisper and still remain clear. I dont know if all the other primos calls can do that, but I know that this one has called in several greys and 'cats for me, also a few coons, but so far only one coyote. I like johnny stewarts pc-3 and pc-1, and my burnham bros miniblaster for 'yotes.
