If I were to set them up from scratch, is the recommendation for a monoplex to take the default of 8 or should maxsystem be set to 1?? Its tough to find any information for the smaller monpolex systems.

But other than taking up more space, I don't think you need to worry about it...especially in a monoplex. Somewhere I think I recall reading or hearing that there is also a slight performance impact if you code 32 compared to 8, but that is also probably for a small sysplex, not a monoplex. Bottom line: Don't worry, be happy.
