M.rubra is compatible with M.alba.  I'm unaware of delayed incompatibility
issues, but don't have any old,old grafts of any M.rubra selections, so
can't make any hard and fast proclamations.
Open-grown trees of virtually any species are going to be more likely to
adopt a wider-spreading, lower-branching habit than a specimen of the same
species growing in a high stem-density setting, where it must grow more
upright in order to compete for available sunlight.

I don't know who's been feeding you BS about ultraviolet radiation causing
short life spans on any particular plant, but it would be my opinion that
they're full of it - BS, that is.
