How do you retain the wing nut to the arrow? With a small bolt? Also, what poundage to you use? I would think that the regular deer weight of 50+ lbs would blow the little fella's up. As a side note, Fred the Weim pictured as my avatar killed two squirrels yesterday. Texas squirrels are a little scrawny for my taste but Fred liked the back legs (sauteed in butter and lightly seasoned) and I salted the skins for use as zonker material tying flies.
