What's the best channel_capacity/network_contribution ratio? For instance, would it be more contributive to open 100 of 0.01 BTC rather than 2 of 0.50 BTC? Also, how do I choose the proper nodes to do this? I had read about triangles, but I'm not sure if that's what I'm talking about. Are there any helpful guiding threads in here?

I just want to increase the capacity in testnet. I have few tBTC lying around (~4.5 tBTC) and I prefer using them in a way to be useful than having them in my dusty cold storage.
