Community pot repotting

[avian]

I have a comm. pot of BLC Rustic Spots. I want to move the plants into separate pots. They are small but filling up the comm. pot. Would repotting each one into 2" net pots or 2" regular plastic pots with sphagnum moss be OK or should I repot them into a bark mixture? I was leaning towards sphagnum. Based on their sizes I thought 2" pots would be the best choice although could go with 3" slotted pots.

Thanks!
