Well, I was experiencing "shoot-thru" as they say. My turn off times were so dang long that the built-in dead times that I had weren't long enough, so both the high and low of each of the 3 phases were on at the same time for short instances, which creates an unholy amount of heat. I feel very sure that the reduced gate resistor sizes will take care of that.
