I graft all my tomatoes that get planted in my foliage-disease-ridden community garden plot, mainly because they're robust enough to stay ahead of the foliage diseases generally, at least enough to produce well for me. I don't always have enough time/rootstock plants to graft the cherry tomatoes that I grow at home in large pots, but when I do, I find that they tend to produce well much longer in the season than when I don't graft them. I recommend trying at least a few of your cherries, zendog.
