I'm still favouring the 300mm f4.

That's an issue with the reduced size and weight associated with M4/3. Even with cutting edge design you still get to the point that larger aperture telephoto lenses will eventually become too unwieldy for the camera, but in this case I don't think f6.3 unnessessarily slow with the latest low noise sensors. I regularly use a 600mm at f8 for birds going up to 16000 ISO without noise that can't be handled with most subjects.
