Believe me, I'm a HUGE fan of both sliderace and MG maps. I've played your servers for ages (think it's around a year?) but this is not like a sliderace map. Feel free to just make a test server (in counter-strike > create server) then type in console the commands I put up there.
Can be on any map really, but best if you use a map that's made for it. You have full control, not trying to get out of the way, not forced to go forwards. Really, try it.
Anyway, I'm off to bed. I'll read this thread tomorrow. Cya =)
