The tubes are called pods in the paintball world.I use to play all over the states back in the day and there for holding extra paintballs while playing so you could reload quick and easy.thanks for sharing because i still have plenty of them laying around here that I will put to good use.Another great idea I wondered upon is the gatorade bottle technique.This is for when you have one tied on and dont want it tangled up in every other rod ya have.Simply take a bigger bottle or a regular size one may work.Cut the bottom out,and slide it down your rod over your eyes and over your rig until all the wires are in the bottle and not dangling out and about.Works great.
