I have been doing it for a long time. Imo, it's the way to grow. I scrog it though to get the separation I want, which is almost as important for yield/quality. Mainlining and scrog are not mutually exclusive, you can use both.
For a true mainline, you would have the plant like pictured above. Thats' essentially what I do. But I don't notice a difference when keeping quality branches that aren't part of the manifold. It seems to be the same. The plant will still send most of it's "energy" to the tops.
So I create the manifold, but if I see strong side branches that are reaching the canopy, I leave them now. We spent the time growing them, if it's a good branch, why toss it? Essentially I think the benefit of mainlining is in creating so many tops, and then allowing them to get most of the energy. But they don't need to get ALL of it for it to be worth it.
If you want to run plants this way, it's an enormous asset to know how to fim. I don't know how to teach you other than search, trial and error. I can't even do it consistently. I fim the fim lol.
Alternating nodes isn't really a problem. The manifolds will not be as clean looking, but the differences in length don't cause issues. Some tops will just grow a bit taller than others, but it's minimal. It won't be absolutely symmetrical, but L will usually be a mirror of R (if that makes sense).
So I'm not truly mainlining anymore. I just top for 4-8 tops depending on the strain, but there is almost always a side branch or two that I keep. So I'm just topping really. What I'm trying to say is that mainlining is the right idea, but imo, some side branches are worth keeping. With my setup, it doesn't seem to be worth it to remove it. Maybe in soil or a slower medium I would feel differently.
In a scrog, growing this way, this is what it looks like at the end of stretch. And imo, it's the best yield/quality. As you can see, they grow pretty evenly. This is 6 plants. All alternating node. Should be 24 tops total (some are out of frame)
