Some background on me. I play (try to collect) all factions. Tyranids is my favorite (1st love) and personally like to believe it is the faction I'm most skilled at using. I won a very local tournament using them and I find that I can build solid Tyranid lists though I prefer building my lists to a theme in general not always aiming to be a tournament winner.

Game Plan: Balanced list themed to support powerful genestealers with gorgon and toxin sacs with powerful shooting from kronos exocrines which I find are very solid at dealing with T7 vehicles and elite infantry. In other games the Gorgon hive fleet has proven very powerful in my standard games so I expect that to hold true.
