Would I prefer a mature tom? Absolutely? Will I shoot a jake if I haven't filled a tag for the season yet? Absolutely. After that, I, personally, would be going after toms only. All up to you. Don't let anybody bully you into feeling a certain way about it. You're hunting for yourself...not a bunch of dudes from all over the place on a forum online. Do what you feel best doing. Besides...jakes taste good!
