Yeh the wind noise is less when I used the Waterproof cover but I found it much easier to use without it.Also since making those videos I've found some more small holes on the bottom of the case that I think are letting in the Wind noise at speed as well.I've put a bit of tape over them and will try it out tomorrow as it looks like a nice day for a ride
Also whilst googling around I know some people have hacked the Mic wires and fitted a 3.5mm socket so an external mic can be used.I have one of those small,"Lavalier " mics

around somewhere so might do that some time in the future.
Then I could rig it to the rear of the bike or somewhere to catch better engine sounds
