Stykbow 67 is right on. They are not looking to breed now so the Toms won't usually answer a hen call.
I have found that locating them and patterning them in the Fall is the best tactic. Once you know where they are and where they will be going for food, you try to intercept them accordingly.
In the Spring, you still need to locate them first, but they are now looking for the girls and will answer the hen calls and a competitive gobbler call. In the Spring using a gobble or hen call to locate the birds in the area is a real effective tactic.
Using a commercial blind is not at all needed. Once you have located and patterned the birds, use your ghillie and/or build a natural blind.
You can use most any broadhead but it is critical that you hit them in the vitals. They are a very tough bird to kill accordingly. Study a turkey vitals diagram carefully.
If you hit one, don't wait for it to die, go to it immediately and finish it off if you need to. I have seen far too many birds that were wounded just get away (and become coyote feed later) just because the hunter didn't go after a hit bird immediately.
Good Luck and have fun!
