I used cattle panels this year. I made stakes by splitting a 2x4 lengthwise, then cut these on a 45 degree angle to get a point, and drove them into the ground maybe 9" or 10" to each side of a row of tomato plants, putting these opposite each other. I put a pair of these stakes every 8 feet or so along the row of tomatoes.
Using bolt cutters, I cut one horizontal outside strand of wire of each cattle panel so I could push the vertical wires in the ground to help hold it in place. Then I put one cattle panel one each side of the row or tomatoes and used wire to tie them to the stakes and brace across to each other for stability. I used hog rings to tie the panel ends together lengthwise but that was not necessary.
I've tried trellisses in the past and was not satisfied. I find that I have to prune heavily or there is just not enough room to train all the suckers and branches to the trellis. I had to tie a lot of the branches too. Weaving was not enough for me with a single trellis. I can't imagine trying just a single stake per plant. Actually I can but probably not accurately imagine would be more correct.
I used 2" x 4" welded wire for that trellis and some of the larger varieties would grow inside the openings in the wire, cutting themselves as they grew. Black Krim was the worst. That's not an argument for or against a trellis, just something I noticed about choice of material.
With the cattle panels on each side of the row of tomatoes with the stakes, it was very stable even in our winds and there was a lot of room for the plants to grow without a lot of pruning. One disadvantage is the height. I had some varieties, Mortgage Lifter and Pink Brandywine for example, that grew out the top and then reached all the way to the ground. That 4' height worked for a lot of them, but some varieties really need a cage, trellis, or stake that provides more height. Do expect them to come out the top and spill over, so you need more room between rows than you might expect.
I did prune some to keep the base of the plants open for ventilation and I did tie a very few but weaving worked for almost alll of them.
