[NAFEX] grafting with rootstock breaking dormancy

As I have only 1 year grafting experience, I have a question regarding using 
rootstock that has broken dormancy - does it have much effect on the success 
of the grafts that the rootstocks are no longer dormant, provided the 
scionwood is still well dormant?

Would chip grafting prove better than whip and toungue in this case, or 
would either work about equally?

We have plum (prunus americana) and cherry rootstock (krymsk-5) that has 
just started to break, as well as a few OHF 333 pear rootstocks we dug quite 
awhile ago.  We still have plenty of pear and apple rootstocks that are 
still dormant, however.  And there are plum, cherry, and pear scions 
expected shortly . . .

Thanks,
Anton in W.Wisc (zone 4a)
