So, the string trellis method is working nicely but you do have to pay close attention to the suckers!! I have 10 tomatoes that need to be pruned and I check them every few days =) As the plants have gotten bigger and taller, I've also started to remove *all* growth below the bottom fruit/flowers. This should focus the plants energy on the maters and keeps the leaves well up off the ground too.
Here's a couple nice closeups:
