Homer listen to R4P here.I agree with him a 100%!But being a versitale caller can change the outcome of a hunt drastically.Being able to read a gobblers mood and interest in your calling tells me what to keep using or switch to something else that might fire him up.I"ve gone from air to friction and clear to raspy before and had a hunt change from going nowhere to a success story.Carry more than one call to the turkey woods that sounds different than your old reliables cause it may just be something ole gobbler wants to hear!
