Also, similar to your experience the grafts make more and bigger tomatoes, compared to healthy non-grafted plants.
I've been using Maxifort for larger tomatoes and Matt's Wild Cherry for cherry tomatoes. A few of the Maxifort still succumb to fusarium in my experience, so I wanted to try the Multifort which is supposed to be more immune. It doesn't seem as easy to get hold of Multifort seeds, but at least I found the Paramount seed supplier.

Paramount also has a seed called Estamino that is an excellent root stock for fusarium and NPK without being quite as vegetative. I now almost exclusively use RST-04-106-T from NE seeds because along with great fusarium and nematode tolerance it is the only root stock that I know of that helps with Bacterial Wilt which is a major concern down south. It also seems to work better with more different varieties for me than the Multifort or Estamino. It seemed to me that every root stock variety I have tried there are a few scion varieties that just don't thrive on that particular root stock and that is true of the RST root stock also. If you find a variety of scion that isn't doing well after the graft either in its production or plant growth try grafting it onto a couple of other root stocks and see how it does.
