tankdriver;
I'm not talking about a light twin flying enroute if that is what you mean. Actually, I like your example of the light twin flying in Alaska enroute just below published Vmc and is a good example for demonstration purposes.
Actual Vmc will be different for every flight. I'm not a test pilot so better stick with the performance tables/V speeds.
Some people keep talking about reducing engine power. Well,again, with many (if not most) twins if you do that during takeoff after rotation, you will not be able to climb. That means not clearing obstacles in the takeoff path. You will find some examples of people who've done that elsewere in the forum.
Also nothing wrong planning a (balanced) takeoff with ASD(R) in the stopway. As long as TOD(R) is within the clearway. A takeoff doesnt have to be balanced by the way.
