One thing to remember with the strutter decoy - if you are not dealing with the dominant bird - good chance the subordinate want come in. Once I had a subordinate gobbler or 2 coming in on string and then see strutter and not get into gun range - I stopped using mature gobblers all together forever. Overall - unless you hav a really dominant bird you are going after - prob not good idea to carry mature gobbler anyway.
I like using decoys - but to each his own. I hav killed more turkeys with out decoys and killed several on WMAs without - but especially if I am on open ground - I use a real wimpy stuffed jake and lay down or breading hen - very deadly if they get into sight.
