I don't like keeping the speed on <10 if high,though I guess it depends how high.You have to slow down sometime and I think 10K is a reasonable place to do so.If you have to go-around at high speed and clean you really have misjudged it!
You have lots more options at slower speed and I think its easier to judge if you're already configured.Also fast you'll be catching the guy ahead at 100+ kts which will impress the controllers.
Slowing up calms it all down and I think that helps the situation.I've seen a high speed approach turn to ratpoo because of a small problem which I don't think would have had the same effect if we had been slower.
Throw in birds/light ac/GPWS/low experience levels/manoeuvrability etc and my minds made up. 230kts/Gear + Speedbrake works 'till the controller decides to vector you for 20 more miles just in case.

250 kts we're on about- not km/hr.hehe!
