Karen,
Reading about your largest tomato ever (1 lb 14.4 ounces)
, it seems you grow them the same size as me. Virtually all of my large type varieties weigh in at 1 lb 12 ounces to 1 lb 14.5 ounces. In all my years, I've only had one tomato over two pounds.

P.S. If you ever get seeds from the duds, and decide they are too late to continue trialing, there's always a home to take in such orphans.
