I wasn't talking about your lights specifically; my point was that it is possible for too much light to be a disadvantage. It sounds like you've got a good setup and have thought your lights out well.
Since we cyclist tend to ride in a similar road placement to what I ride...at least the ones who still have a 3rd dimension
...I feel that the "you might blind the motorist" argument doesn't hold much water. Most people don't have the fire power I have and I feel that they'd be hard pressed to do more blinding then I can.
There are situations where blinding a motorist is not only helpful but necessary. A helmet mounted light swept across the eyes (if necessary) can go a long way towards stopping those beast. I would never advocate doing it on a whim but there are times...even for me
I know that they are going to have a blue dot in the middle of their vision to remind them for a while
However, in normal urban lighting conditions, having more light makes you stand out against a rather light crowded background. More is always better, in my opinion.
