First off, I admire your enthusiasm getting into this type hunting.
Second, it can be tough, but hang in there and you will make it happen.
Now, I am NOT telling you how to hunt, nor am I an expert, but I do have several birds under my belt. This is just something for you to think about.
You say you want to shoot closer than or max of 30 yards. If you can't get them that close you would just come back later.
I know you would like to have your birds at 30 yards or closer every time, the rest of us would too. But the fact is, even the best callers in the world can't force a tom to come to their calls if he isn't willing.
You never know what will happen, it's great to want to have them at 30, but why not be prepared for 40 just in case? Would be better to be prepared and not have to shoot that far, than need to and can't..... especially if you have spent an hour or two walking and/or working a bird just to have him hang up at 40 and you not be able to take the shot because of distance..... then leave empty handed.
My thoughts, and my thought only: If I'm putting in the effort to make it happen, I will do everything/anything, I can to take that bird for a ride in my truck. Being prepared is a comfort to myself.
I wish you the best and good luck this coming spring my friend!! It truly is a test of patience.
