Take wildcard's advise and get a loaner at one of the games.
But a hit is a hit and you should be out. If you think you got hit call yourself out even if you didn't. This will only help you in the airsoft world as players will know that you are honest.
No matter what you will encounter the "Terminators" of the game that no matter what will not call a hit but you will soon learn these players and learn to deal with them.
