Granted, I am quite new to airsoft but my principle is LESS IS MORE and focus on being agile as I play CQB. Concerning clothing, anything really goes!
The thing I like about CQB is it can be the guy with the old shitty hoody & battered AK which is better than the people that have all the MilSim kit. You really have to approach all players with an open mind and not judge until you see people actually play!
Also, I would like to see more threads on game play and techniques!
