QB map question

[Floki FGM]

I've read the guidelines regarding QB's because I want to give my opponents a good FAIR fight. So I have a question regarding the maps used.

Do you guys play on different maps or do you like to play a select few that you like? If you've played the map before should you tell your playing partner or is it just assumed that most guys have played the map and are familiar with it.

I just started playing QB's and already feel that I'd like to play a map over again just to try new things out.

Input from experienced players please.
