Betsy,
After years of fighting with persimmons, I don't want any side branches
with buds higher than the graft union.  I'll usually just break 'em over -
leaving them attached - at some point so that any buds on the 'sap-drawer'
are lower than the graft.

YMMV.  Apples/pears probably not so ornery as Diospyros...
