About 2-3 diamond, Parallel Universe Monkey might help, because Bloons are coming from the left and right sides of the screen, though I haven't tested it yet. It depends whether diamonding 2-3 is your main objective. If you're just trying to collect more Golds/Diamonds in general, I'd say get Spikey Chaos first. It's by far the best ability yet.

Double Doom isn't bad either. I tried earlier and diamonded 2-3 with Precision Flight+Parallel, using Spikey Burst and Double Doom, using no epics.
