I use Primos cow calls. Not only can you call bulls and cows in closer, you can stop them for a moment for a decent shot if they decide to head the other way.
I use Carlton diaphragm reeds. They take some practice but sound great and I can control the pitch, length, loudness, etc. cant do that with a hoochie momma. The single reed is good to start with but the double and triple reeds are where its at.
