Mainlining 2 plants in a 4x4 ft tent: how many tops?

[Gurtgurt]

Right now I'm trying my first hand at mainlining. Each plant is identical in nodes and currently has 8 tops -- except for one, it has 7 after I broke one.

My question now is, given the space, should I stick with 8+7 tops or go ahead and cut each to 16?

They are already growing slowly but that does not matter to me. I have a net, but was thinking not to use it as the space is not very accessible. There are 2 sf2000 led panels 200W each. The strain is LSD.

I suppose the tent is 16 square feet; 4 feet on a side. Woops.

When the branch is trained to grow sideways tops sprout up off the arms aswell. Just keep it going wide.
