Hi Sal,
the airlayer thing is fun . Im sure soon you will have another panache plant.
I hate to beat a dead horse but if once you have another and want to experiment with the parent plant cut the top growth off one season when you still have lot of growing season left.
Im not trying to sound like a know it all only i go by what i seen in response
in my plants.
When sometimes our fig plant grow like whips its best to cut the top because those buds on top have the apical dominance and keep most of the lower nodes "dormant" and not sprouting anything or very minor. Most will grow and look like if i may a palm tree with a skiny main trunk.
By cutting the top of main your sending downwards the energy (Auxins) that will get plant bushier down lower.
Either way i hope to see pictures of your airlayer and eventual fruit, i hope mine makes it out of dormancy and fruits this season and we can share pictures.
