If you like big and sloppy pineapple should suit you fine. I haven't found too many really tasty with nice texture yellow tomatoes. Lemon boy was a nice tomato in my garden, though, last year. BUT it isn't an heirloom.
Big beef is a huge tomato in the early season. Goliath... is not goliath, but a nice sized earlier than most slicers tomato. Marglobe is an OLD variety that is very tangy/acidic if you like that type of tomato.
Have you tried any of the green when ripe tomatoes? "Summertime green" is a good one that is a "dwarf" tomato, staying under 5' tall. in the garden.
