From cutting to tree, you have a long trip. Cutting Vigor is a great sign, but has nothing to do with productivity. You will need about five years to really know which one is a real winner.
In some cases less. Sometimes things are touch and go and some varieties will not produce before three or four years. It's all about patience and there are many variables at play.
If you have some FMV symptoms on your cuttings then growth might be slow and in some cases, I would try to find an FMV free strain if possible.
If a cutting is not good enough for me to keep then I would not give it away, I prefer to destroy it:)
