It looks like that tall lanky one that split you tried using one mode for the entire plant? Do all the colas come from that one node?
I stripped off nodes 1 and 2, and topped above node 3. The 2 branches that popped out of node 3 were topped above their 1st nodes, and those 4 branches were topped above their 1st nodes, leaving the 8 branches you see there.
So everything comes out of node 3. Thats how I manifold all my plants. All 4 of these were done that way.
Technically it was topped above node 3, those 2 branches were topped above node 4, and those 4 were topped above node 5.
All plants will give you at least 5 nodes of opposite phyllotaxy (unstaggered nodes), most 6 so you can easily get to 16 level tops before alternating phyllotaxy (staggered nodes) start, and about half of the strains/phenos I have grown will give you at least 7, so you could go to 32 equal tops if you wanted.
I tried 16 and it was messy.
The tops were too close together and some got lost and went runty and got pruned out, leaving an unbalanced plant.
They still grew really well with 12 or 13 tops each but some areas of the canopy were mangy and crowded, some OK.
8 per plant giving me 32 tops total usually ends up in 1 or 2 runts still getting pruned but overall I find it a good balance between a manageably full tent and nice big colas.
Then as different phenos are taller than others, you simply toss a spacer under the plant and raise the whole thing to make all 8 tops even with the other plants, or pop a spacer out to lower a lanky pheno.
This grow is actually on the sloppy side. Moving them all from the flower tent to the veg tent and back to the flower tent destroyed their normal training regiment, but they still came out fairly well.
Then as the tops veg out you remove side branching up to your desired levels so you don't waste pot nutrients growing out larf and head into flower.
I have wires running just above pot height around the 4 outer edges and across the middle that I strap the boughs to to get them into order. I use green rubber wire for the hooks and green twist tie for the wires on the tie-downs.
I don't tie them to the wires, I only bend the twist-tie once over the support wires.
That way if stretch pulls too hard or some stoner hooks a wire with his elbow they release instead of breaking a branch.
I also run cross wires just below the light to tie support hooks to so I can support or manipulate colas.
