I think lots of things must be changed in the actual Surf Gungame Server.
Maybe the server mod change has not been appreciated by everyone but I personally like it and I play it quite often.
So my suggestions are :
1) Remove the parachute. It's pointless to be able to use a parachute in a surf server. Don't forget that the aim is still to surf.
2) Fix the fact that a spectator is revived and can be killed by any team. It's really annoying for the player who will come back and won't be able to play and the fact that any team can kill the bugged spectators just gives points/levels unfairly.
3) Add more maps because it's starting to get annoying to play the same 4/5 maps every time.
4) Change the order of guns because I think that for exemple, the scout should go just after awp and not after m4a1 or w/e (forgot the gun order).
5) The last weapon should not be the nade but knife only.
6) Add a shop system. This would be good to be able to have some advantages after saving some points.
7) Add a system/plugin who would open the cage automatically (except in surfgreen indeed) in order to avoid cage campers who go there only to backstab you (most annoying part).
I think that's all I had to say.
Cheers.
