There is another factor to consider in this scenario, how much airspace do you have avail / want to use. My preference is to level off, slow right down , get as dirty as possible, as I prefer the radius of turn / time / that I have at Vref 40 - 162kt rather than guzzling track miles @ 310 or more. If you are in turbulence ( try a Kanig arrival to LEGE with a strongish Northerly wind) it is going to be a bit kinder to the airframe too if you avoid the very high speed stuff below F100.With 737 cockpit noise levels, it is also easier and less stressful if you can hear your other crew members anguished comments on your profile ( or even the aircraft's profile. . .) while you sort it all out.
