RE: snuffer or zwickey/sightpins or not?
If your Zwickeys are sharper and fly good don't hesitate to use them. The two blades will be more than sufficient if you place the arrow correctly. I don't use sight pins just because I don't like messin with stuff, I just like to shoot. Don't have to guess how high or low to hold the pin either. For huntin I keep it at 20 also. With a little more practice I may be able to move it out to 25yd, but 20 is good for now.
