Just got one from Wiggle. My head is long, narrow and 59cm so in-between sizes. The helmet fits (just), but is not perfect.
Take Hippy's advice, and test before you buy. Not sure if 5 minutes in a shop will compare to a long Herne Hill session in the sun (or your not doubt more strenuous commute), but better than nothing.
Prendas currently have the Whisper on sale for £99
