After having most of my army list ideas shredded into continually smaller pieces, I'm going to take shots at starting fresh with my 'Nids lists.
I'm seriously leaning towards a Psychic Choir, with a 2 Tyrant HQ, but I'm not sure what the best troops choices would be? Packing in Genestealers with carapace and flesh hooks seems like a good way to make sure they get across the board and make an impact, but part of me looks at how many stripped down Hormagaunts I could put onto the table at the same points costs.
Is there a general way people tend to fill choirs out?
