With my 40MZ-2 I already have the option of using a small direct flash and the big flash for the bounce, with just one flash unit. Using a filter on the small flash allows me to control the output of the small flash. It comes with two different filters, so it gives me three options. One is without a filter, which has about 10% output of the small flash compared to the bounce, using the filters brings it down further. However, this doesn't give control of the ratio of the contribution of the small flash versus the bounce, unlike the RTF/bounce combination. The advantage is that it is done by the flash alone, so it doesn't require a lower flash sync unlike the RTF/bounce solution.
