Toms side shoots and topping out?

[Spookyville]

My toms in green house are goig mad and have reached the roof now! I did not take out any sideshoots (newbie error) and some plants have 3 or 4 main stems plenty of flowers on.
They are Gardeners delight and shirley. any advice or guides on how to top them out and stop them growing to try and rectify the situation.

also have some tumblers in baskets which are now tumbling all over - presume these can be left and not pruned in any way...

TIA

Oh, dear!!   How tall is your greenhouse? Look at it this way?

1. You will only ripen 8-10 trusses.

2. The trusses on the main stem will ripen best. Shirley produces very heavy bottom trusses.

3.  The lower side-shoots will do better than the upper ones.

4. Unless you want to train along the roof, you only have height for X trusses.
Pinch out the top shoot when those prameters are met.

5. Take out unwanted sise-shoots.
