RE: best arrow shaft for small game
You can find some great deals on ebay for gold tip carbons, bemans, and easton xx75 sized arrows. Cabela' s also has inexpensive " stump shooting" arrows for around 36 bucks a dozen delivered.
It would depend on the arrow for the size fletching. I use my normal hunting arrows for small game, but also dug through the old box of aluminums and found a dozen straight shafts that I had fletched up with 5" veins. Normally I go with 4" on carbon.
