Lot's of discussion on BNuts on what kind of starter material can actually be achieved from an airlayered branch. So let's see what kind of material you find worthwhile of not just the layer, but the years of development that will need to go into it. (No ground layers please - we know great material can be obtained from a ground layer). Are branch layers simply free material that will require tons of work, or can more special starter material can be obtained in this way?
