Ready to top my first mother, any advice?

Well after looking around other threads about mother plants and clones, I still unsure on how to make this girl a perfect mother for my future SOG activities.
She is a two week old top clone of a Trainwreck. Shes growing fast now and there are shoots at every node. I need to keep her short as she will be sharing 5 sq ft. with 2 more moms and some vegging clones. I'd like to get 2-4 months worth of cuttings out of here then she goes outside to flower. Looks like shes about to explode an id like to flower that bushy top after some lst and a short veg. Topping at the second node would give me a more manageable plant with my height limitations I think. Could any explain any advantage to topping at the third node? I also read not to take the top too late before the leaves get to big, which is happening day by day. Any suggestions are appreciated, thanks.

Try to FIM it. You will end up with a nice little shrub you can take many clones from.

Wait till about 6 nodes have grown then take a cutting of the top at the 4th node, this will give you 6 cuttings next time and so on every 2 weeks.

@*BUDS That's what I thought about doing at first, to get a good clone to flower immediately while the mom is vegging.

At the same time if I fimmed her now I could get a jump start on training the mom for my purposes in my limited space. 4+ main shoots could supply a great amount of cuts as well as topping. Also at the rate shes growing I could probably get 2-4 cuts off her within the week if I fimmed her now.

Decisions, decisions...
