I prefer 1-1/2 - 2 pounders. But I don't think I've ever had bigger. Wait, I did have a cooked claw from a homungus one that a friend gave me -- it was very good, but not enough. ;-)

Best I've ever had (pound and a halfers plus) were from a lobster pound on Long Island in Casco Bay (just off Portland, Maine). Ah...fond flavorful memories of those lobsters.
