Both!
Wont it be easier for you to build a feather Craig as you can use it when at an event with Saint where as, if you build an ant, you will have to go to another set of events.
In my personal opinion, even if you don€™t build the feather yourself, over time you learn allot more about how they work etc. compared to ants, (I made my first one and had no idea what I had done, worked though!)
