Thoughts Please - Pruning

[PNW_D]

I'm sure there are many such threads, but couldn't find one that quite addresses this question ............ (from my bil)

The tomatoes are doing great. Well...maybe better than great. The tallest is over 4' tall. And the two Kimberley's both have green fruits. Here's today's question: I know that you said that you were not a 'pincher'. But on the indeterminates, I have been pinching off the new shoots that formed in the 'elbow' of each branch. I originally attempted to keep to 3 main stems per plant...but having missed the odd one, each plant probably now has ~4-5 main stems. But now that they are forming blossoms, each time a 'blossoom branch' forms, the main stem splits into two..or three. Since these were not in the classic leaf branch 'elbow', I have not been pinching them. But things are getting totally out of control. I have been raiding Ruth's nylons to cut into strips to tie the stems to my trellis...but she's running out!! Plus I would rather have fewer fruits that reach maturity...rather than a ton of green tomatoes. So should I be pinching some of these off?? I have attached a couple of photo's to show you what these 'stem splits' look like...

And have a look at this extreme pruning method - took pic today at a wonderful allotment garden
