Sounds great. Will definitely try it.
My Cherokee - just the one - didn't perform spectacularly, but I had no cracking this year. The Brandywine grew enormously tall and brought forth two tomatoes all summer. Bananalegs peaked and fizzled early. San Marzano performed fairly well. The striped Germans and grape tomatoes were as reliable as usual. They're pretty much all sick now - molds got into the mulch and all over everything - but I'm still getting a few fruit.
Next year, I'll take care to space them better and hold off on the mulch. Maybe just stretch netting over the bins to keep the cat out.
