I wouldn't trust most of the shit on that site. I'd rather go to CDG, since most of the guys there research their shit before doing a simple wood reskin (most are crap on FPSBanana) and say "ZOMG MY SKIN RULEZEH!"
There's only one pack I use for my skins, and it's for allies, and that isn't found on FPSBanana anymore. Plus I wouldn't add any custom shit to the server, it's just a longer dl.
