I am finishing up the new Micro singleton FuzzBuster that has some similarities to the cluster EI phages. I have not called a Major Capsid, but about half of other annotators call pham 10363 (FuzzBuster_31) a Major Capsid. I don't see any evidence for this and feel I should get nice HHPRED hits for a Major Capsid. I am not sure if this was called based on synteny alone, but perhaps I am missing something. I am leaning toward NKF.
