best training/pruning practices for tomatoes in green houses

Hi y'all, I'm curious how you manage your greenhouse tomatoes.  I usually aim to prune them to a single stem wound up a long strip of sheet secured up in the rafters, but I inevitably get behind on the pruning and end up with a chaotic mess.  Also, I know there's a way to drop the plants down when they start to get too high to reach, but I haven't managed it yet.  Hoping for some inspiration or maybe a new direction/technique for next year.....

I grow dwarf/determinate plants in my greenhouse. No staking/trellising required. All the professional-ish greenhouses that I visit, prune to a single stem wound onto a hanging twine.

I grow a mixture of determinate plants and indeterminate the indeterminate plants I prune to a single stem and wind them up string. My season is not long enough to need to lower and lean. having half the plants being bush tomatoes helps with the pruning load although I do go through them a few times to make sure they don't get to big or try to set fruit to late in the season.
