F2 or F3?

[Labradors2]

I'm bumbling along, trying to capture "taste" and "dwarfism" in a bee cross. From my limited trials, it seems that taste shows up in the F2 no matter what kind of leaf or tomato shape I get .

OTOH dwarfism is proving extremely difficult to capture. Twice, I planted 16 seeds in a pot, but couldn't detect obvious dwarfs, just smaller seedlings that were a little later to germinate!

I saved seeds from the best F3 to go forward, although I only grew 6 plants. It had uniform great-tasting saladette-sized fruits, was quite productive and didn't grow excessively tall in a container.

My first question is, should I go forward with the F3 seeds next year, or try again with as many F2's as I can find space for?

My second question is will the great taste stay, or will I have problems as I proceed with more growouts?
