Sure thing drphil.
Firstly, to understand where I'm coming from, you need to check out this thread - if you haven't already seen it:
figs4funforum.websitetoolbox.com/post/air-layers-greek-style-6827365?&trail=50
Even if you only skim/scan it, you'll see that I have a penchant for doing things on a grand scale. So ok, this one is quite a bit bigger than my usual fayre, but the 3 subsidiary layers on this tree are generally the smallest I would consider as being worthwhile, bearing in mind effort, cost, etc.
To me, the whole point of a layer is to end up with a small tree at the very least, if not a mature one, that will yield ripe fruit in its first year - 2nd year at the latest. A layer made from a young shoot is not gonna do that for you. You may have to wait 3-4 years (maybe more) before it yields anything useful.
If all a layer does is give you a runt that's not a whole lot bigger than a cutting, then I would save time & money by going for the cutting. The only consideration then is where I would draw the line between the two, but that's another story. Maybe I'll illustrate sometime with some pics to show you roughly where my line is.
And Aaron is right - a pic would be useful so I can assess whether it's big enough to make layering worthwhile according to the yardstick I use to judge such matters.
Hope that helps, otherwise let me know if you have any further ?'ns.
