I am going to be the odd one out here and say – I THINK first of all that the communication issue is only one of your voice, however there is a good chance of you SIGNALING to back players what you see.
Having said that, I believe the snake might not be the “ideal side” for you, since you might be out of sight to “signal” something to your other players (when getting started in learning how to play), and not being able to hear all information on the field will leave you in the unknown as well. Hence I would suggest you try the Dorito side to start with and work with your team on signals that are not too intrusive during your game play, however get the message across, since we are already speaking via mail and text it’s something we can maybe address at the next training when we start putting a team together. Once that works you can start trying different positions on the field and find the one you are most happy and successful in, since in the end you want to enjoy your sport and not get jammed into a role you might not even want to be in.
