You also need to downgrade packages back to unstable when the build
needed some package from experimental. So you should pin to >1000 and
run apt-get dist-upgrade between builds as a minimum.

Or just throw away the chroot, unpack a new one, upgrade to sid, add
experimental to sources.list, run sbuild for every build. Much safer
and simpler.
