But, I see now, you are already familiar with the above discussion, and the advice (addressing your query) provided within it.

Rifis I just went through that thread and I honestly didn't see where this was addressed. I recall a discussion about how to encourage more basal breaks but that isn't my issue - some of my plants have 5 basal shoots but they're all growing straight up in a tight group and the plant is still only a foot wide. I don't need more basals, I need them to branch out laterally. Would a really severe haircut in spring encourage that?

Try tying the canes horizontally (you may have to install a couple posts with a strong wire/cable stretched between them) so laterals will be come out along those canes. You can even tie the laterals down which will produce more of them.

When a rose is naturally wanting to grow tall and lean, wait until the spring and then prune it down by a half. You can just go straight across the bush or you can cut below an outward facing bud eye. Both ways will give you a fuller bush. You will probably have to always prune it back hard in the spring.
