We consider novel ensembles in the D1D5 CFT and find a new phase with a larger entropy than the BMPV black hole (and indeed all known bulk configurations) with the same macroscopic charges. To understand the fate of these states at strong coupling we conduct a systematic study of (two center) solutions in the bulk (AdS3xS3) with the same macroscopic charges but with different dipole charges and find a corresponding new phase in the bulk. In some regime of charge space these multicenter solutions dominate over the single center BMPV providing an N=4 analog of the N=2 Entropy Enigmas of Denef/Moore. This phase however has much less entropy than the CFT phase suggesting that most states lift at strong coupling.
