Hummingbird Network Activate or individual site Activation

So, I am very interested in Hummingbird. I have not really gotten W3 Total Cache to do what I wanted, and it seems like Hummingbird should.

I would like to control most of the settings from the Network Admin dashboard so I activated it for the network. (I assume all optimization would apply to the entire network, correct?)

The downside to the network activation is that the Uptime Monitoring gives an error. Unfortunately, I can't seem to find access to any Hummingbird features on the individual site dashboards.

Do I need to just use individual site activations?

Thanks guys, keep up the good work!
