You can work this round and the next one also using two shuttles. When moving to the next round, switch the shuttles to change the direction of the chains.

All chains 4-3-3-4.

The second wing (starting from part II) is the first wing's mirror image.

At the time I designed this one, I didn't know much about climbing out of rounds using split rings and chains. I leave it to you to come up with a better way of working this butterfly to avoid cutting the threads!
