So maybe I shouldn't sell my Sunpak 422d, which has a power scale,
and sell the 'extra' T-32 :) I was going to sell the 422d, as
I hadn't been using it.
I was thinking that the umbrella would diffuse the light, and this
would give a more subtle fill from the side, rather than using
the T-32s all firing directly at the subject. Has anyone compared
how this might work?

As I understand the way the ttl system works, since you are connecting
the flashes with a ttl cord, the camera does not know that one flash is
bounced into an umbrella and another one is on the camera. They are
both just one flash to the camera. So, the camera will turn off both
flashes at the same time when the proper exposure has been recorded.
The ttl system measures the light reflected from the subject via the
light reflected from the film. So, there is really no way to be sure of
the light ratio on the subject. You would be better served by using a
remote flash that has a manual variable power setting and slaving that
via a light sensitive slave unit. You would still have to guess or do
some math to figure out the approximate ratios, but it would work
better in my opinion.

There are such things, I have one. It depends on the manufacturer of
the umbrella stand whether or not such a support is available.
Be seeing you.
