Yes loobs are broad but even so there are a small area
in betwen two main loobs that are quite a bit down.
I´ve been using an 8 direction 4 square vertical array
on 80m for 30 years and on stuff right in the middle
of two main loobs I can see up to 10 dB difference.
This is something I built myself, at one time I also
had a 4 sq 8 directions on 40m.
Anyway, I would not like to be without it.

I know that RA6LBS makes good stuff so that might
be a good source.

Gary,

We are selling those 8 direction systems since 2007 at least. This is what
my records says.
And we only sell items I tested myself.

Those who can make A/B test between nearby “standard” and “new” directions
can tell you how important it is to have just few dB difference. Copy/no
copy  in some cases.

At the price of few more control wires and something like 50USD for extra
parts only.

A couple of companies, LBS and RemoteQTH, have started selling 8 direction
4- SQ controllers.I'm trying to understand if this would be worthwhile. My
reasoning is that the main lobe is so broad you have the in-between 45
degree directions covered anyway. Thoughts?73,Gary K9GS
