What settings do you use to cut down render time (med quality) in a crunch???

[heni30]

I have this client who is going to want a 36" final board for this rendering. He is always making last minute changes so I'm trying to use settings that will cut down time drastically and give me a medium quality image that will be used for a meeting presentation.

 

What res do you use? I use 200 but will 150 do the job?

 

I know there's lots of info out there but I'm always interested in individual approaches.

 

Thanks!
