Chapman flavor

[Chrysos]

I have a chance to get a "Chapman" tomato and was looking it up here. Lots of posts but not much about the flavor Looking for a not too late sweet beefsteak. Like Brandywine sweet Tp be specific, words like "tang" and "old time tomato flavor" in my experience tend to mean different things to different people. Sounds like it's resistant to blight which would be great. Last year I used valuable tomato space in my garden for a few hybrids, never again! Big beef and Fantastic were lovely healthy tomatoes, and I gave them all away I do need blight resistance (I'm in the Pacific NW) and great sweeter taste. Any suggestions welcome
Thank you!
