For productive tasty slicers, My best all around are the TSWV resistant varieties Saybrook, Mountain Merit, Dixie Red.
Tomato (Solanum lycopersicum 'Saybrook') I have extreme disease pressure especially TSWV,. There are excellent varieties that I cannot use because of it. Mountain Rouge is especially tasty, but has low resistance to TSWV
Tomato (Solanum lycopersicum 'Mountain Rouge') These are all big determinates. Big Beef Plus is an indeterminate with a huge vine that does well. The big vines require a good deal of labor to manage.
