i mainly play at SHA, i have played at arena in grimsby (i was a member, i dont recomend, but they have changed it so it may be ok now ), LAC (great sites though combat zone is abit of a trek). Elsham is great, i cannot wait for the next game day!!!
i have played 1 game at humber, and i was a little put off (it was over a year ago mind, and its a personnel thing)
i have not played at headshot.
for a complete beginner i would recommend SHA (slaughter house), if not for the fact that its close by, its because i play there on a serious note hire guns are available and not too expensive, games are varied and not too long etc its great CQB, but i am a little bias i think the only requirement is that you wear foot protection with ankle support (most sites require this). the only limiting factor of SHA is the fact that sniping is very very limited, it is a CQB site.
