It isn't so much a specific combo as ANY combo. Whatever varieties you happen to be growing. If you are growing only 3 or 4 varieties then mix them all. If growing 30 different varieties then it's even better. :)

I've made some great sauce using San Marzano, Beefsteak, Brandywine, Eva Purple Ball, German Strawberry, NAR, Opalka, Sun Gold, etc. well you get the idea. The more the varieties, the more complex the flavor.

Most of my tomato friends switched from using just paste tomatoes many years ago b'c the taste of most of them, with some exceptions, is not great, they're more susceptible to BER ( blossom end rot) as well as Early Blight ( A. solani)

I could list the paste varieties that I think have great taste if you want me to but I also know that there are many many threads here already with those suggestions.

When choosing what to use to add to paste tomatoes for sauce I strongly suggest using as many heart varieties as you can b'c they have dense flesh and few seeds and great taste/ And also dense fleshed beefsteak varieties for the same reasons.
