Hmmmmm, best calls!! Well, not trying to be a smarty, but the best calls I use are the ones that work at the time and place. I believe all calls, will work eventually. I've heard too many different guys use different calls and seen pretty much all of them work. But, the guys that use open reed calls seem to call in more than any other calls out there, including electronic and closed reed calls. To me, electronic is too repetitive. Some closed calls do sound pretty good and have worked for me in the past, but nothing holds a candle to the open reed calls. I like the two calls from Verminator, Tally-ho, Carlton, and Critter-gitter calls. Don't over look a good Howler or two also. Most open reed cow horns sound pretty good and I also like the Red Desert Howler. As for which tapes work best, well Coyoteseeker uses group howl with success to locate coyotes early mornings, and most have success with cottontail distress, fox pup distress, and jack rabbit distress to name a few. But, again, my money is on open reed, period!! Good Luck!!
