Hi, can anyone give me a suggestion for a reasonably competitive Tyranid list. I feel like a new project now that my guard are finished (ish) and thought that collecting some oop Tyranids would help me waste time and money on ebay for a month or two! If there are any veteran Nid players out there I'd love to hear about what you're putting on the table.

EDIT: Just spotted the list threads. Sorry. Delete away mods...
