Fall tomato growers, replant or keep alive?

[Dewayne mater]

In the next week to 10 days, I'll pick the last of the good spring tomatoes. There are some new ones growing a maybe I'll get a few more, but, they are going to be small and will have very thick skin as a result of the coming heat. So, this year it appears I'll have the option to hold over the spring plants or pull them and start over with new transplants.

The existing plants are tall, and the top few feet are very hearty on probably 2/3 of them. This may or may not be a good thing as many are so big/heavy that they have topped and are bending Texas Tomato Cages, and some have already grown back down to the ground at started back up!

I have transplants available of varieties I like, but not near as many as are currently growing.

I know Ted like to keep his plants a full season, but others in hot climates start anew about now. I've been maintaining my plants though the season and some, not all, will start to produce well again when it cools off in October. What do you do and why? Thanks.
