As a general rule...?

From having a trio and getting a fourth bun in the hopes of evening up I'd say wait a while. Bonds change months into it. I never did manage to get them into a four and though every now and then I think about I don't think I will try now. You're more likely to end up with two pairs IMO.

Thanks for the advice

I think I would only consider getting a fourth bun if I felt one of my 3 was really excluded in the bond. But you're right, bonds do change and hopefully Cupcake won't be left out
