Thanks Greenfin!
Jds, I have another of the same variety that I pinched heavily and it stayed under 4'. Both produced one fruit, which has yet to ripen, all other figlets that are forming last couple weeks are pinched off. I wanted to compare production of step-over versus tree, looks like it will be next year to really get a good comparison. Believe me, I want fruit too.
The idea on the step-over is that the laterals (uprights, I'm not sure why they are called laterals) are supposed to be branchless. Two did decide to branch way up high.
I am looking for more land close by for a proper orchard, my little piece is nearly full of plantings and mostly part shade, so yeah, I am propagating like mad. I am teaching myself to form them properly, so I'll keep the very best for planting in ground.
Tyro, Yep took your advice, I try not to get into hurry with airlayers. You are the major inspiration to me learning how to shape them as well.
