There is, as they say, more than one way of "skinning a cat".
I am not advocating that one should never exceed 250 kts below 10,000 ft. There are occasions when this is quite appropriate.
Remember that angle of descent depends on the lift/drag ratio (and not just the drag). If you increase speed then lift AND drag will increase - what happens to the lift/drag ratio is somewhat debatable although, I agree, application of speedbrake will change this.
Perhaps we have drifted a little off the topic of this thread but nevertheless it's an interesting discussion.
