I'd much rather have a bunch of roots and no shoots, than shoots and no roots. I've never had a healthy, rooted cutting not produce a shoot. It seems unlikely that no buds will break on a 7 1/2 inch healthy, heavily rooted cutting (3 nodes?). If the buds are alive one/some will break - it might just take time.
If you're having trouble telling top from bottom, the buds must not be very obvious. I've noticed that in a case like that you may not get much warning - no obvious bud swelling or greening. It doesn't look like it's doing anything, and all of a sudden there is a tiny green pinhead popping out of the bark. It's so small that I usually wonder if my eyes are playing tricks.
Kathleen's Black sounds like it's healthy - it's probably just on it's own schedule.
