Hi Brian!!!!!
As for colors.....anything BRIGHT!!!!!!!!!!
I have been using Chartruse/Blaze Orange for a few years now,Joe Skipp's favorite is "PINK",Lots of guys use white.....
One thing to remember is that it's very important to be able to track the flight of your arrow both before and after the hit,because you must find your arrow after the shot to determine a hit or a miss.
If your worried about blending in(i.e.Fall colors) yellow is VERY good!!!!!! However.....Be warned,trying to find a yellow fletched arrow in a carpet of fresh fallen Sugar Maple leaves can be VERY frustrating!!!!!
As for left or right wing.....Personaly,I've never seen much differance.
