Ed Mashburn can help you find resistant ribes.  I think it's safe (where
legal) to grow immune ribes along with white pines.  My husband's uncle
has an illegal current patch in pine country in the catskills that
predates the ban.  The numerous pines suffer only from logging and
deer.  Most of the state bans have been selectively removed recently for
immune cultivars.  This is partly because of shifts in the relative
value of pine lumber and unusual fruit (in, for example, Massachusetts)
but also reflects new scientific study on the subject.
