Graft union height can change the ultimate size of tree and the yield,
depending on the rootstock. It may also change the winter hardiness. (I
recently read somewhere that trees grafted higher onto antononvka (if I
recall) were more productive.)
In the situation with 111, I doubt that there would be any drawbacks to
grafting higher except that if rabbits do some damage you may have to
regraft.
What had you read Tanis, what were these "dire warngings"?
