Curious to see where you get with this.

Also curious to know, are you doing this because it can be done or do you believe that it's better to do this way?

The reason why I ask is because I am of the mindset that more rigs with less cards, like 6-7 per rig is easier to manage than one huge rig, especially when you have a card or card(s) that are giving you grief.

I see some potential power benefits of running one huge rig versus several though and less costs overall to startup a new rig or expand an existing one but if the rig is higher maintenance long term because of its size I would see these gains being lost due to lost profits from downtime.
