The heavy duty round tomato cages (4 rings) work pretty well here .. BUT they need to have 1 or 2 stakes driven well into the ground that helps to keep them upright. I use cut up trouser socks or thicker pantyhose for tying the plants where needed. I found a bag of the loops used for the square weaving that kids often utilize for weaving for potholders - they sell cotton ones and nylon ones - and the bag I found was nylon, so I'll be using those as ties this year.

@BReeder! I found trying to buy the fencing a bit costly, for what I wanted, so I went with the round cages.
One of the best tomato supports I've seen in use, was in windy eastern WA - high dry desert area. The woman (a retired rancher that sold her xx ranch acres and bought a 10 acre plot for her and her husband for their retirement) had a large garden plot, with these supports. She found the instructions in a magazine many years ago. Liked them so much she reproduced them again for this retirement phase. Basically envision a Y with a center post. These are the ends and middle, and these Y's get set into the ground. Now add horizontal connectors between the Y's - several up the vertical axes. So, they get wider on the Y, but can also put some on the center axes. On these horizontal connectors, can hammer in nails or use screws - in pairs - to provide a place to add another level of horizontal connectors between (and perpendicular to) the two sides of horizontal connectors. the nails/screws do not attach the two pieces together, rather, they are there to keep the boards between them, and the boards can be moved out or in, depending on where or how wide you need support. At the end of the season, it all stores flat, the "Y" ends/middle are flat, all the horizontal supports are flat, and nothing was screwed together (other than the Y's). Of course, wood is pretty pricey now, but if can source cheap or free lumber, then it could be an easy/reuseable tomato trellis system. We have not gotten around to making them, but hopefully we can make them now that we have things set out more where we want them.
Brandywines - stopped growing them, was never that impressed... might try them again at some point. I recall growing Purple Cherokee that tasted quite good, and was similar to a Brandywine, but with better production for me, but haven't grown those in a while either.
