I hear you. The GSSF team is fun, and it's also novel that we have a GSSF team.
Jerseys and fancy expensive guns don't make me want to run away, they just make me want to race and see if I can win or keep up. Many skill levels of USPSA competitor like to wear jerseys. Not my problem, and not theirs either. If a person is burdened by what other people wear...they are the one carrying the burden.
Kind of a tangent, but which stage are you talking about where the GSSF jersey guy shot the targets near to far? I am always interested in the persistent differences between how I and some of my competitors deal with the stages in GSSF.
