Scrog and LST

I know this has all been covered here but I am having a very hard time figuring it out. I have 5 plants in a 3x3x6 tent with a 600W light. They are short and bushy and looking very good. I have them in 5 gallon pots and I was wondering if I should set up a Scrog in my 3x3 tent or do toping and heavy LST? I am worried the plants might grow a bit to big, bushy wise, for a scrod in my tent with 5 plants.

Each plant can fill a 2x2 no problem, with a decent veg cycle. Youll be overcrowded in a 3x3 for 5 plants.

Sounds like a mainlining would be more for your space
