I would also go with Brian's recommendation of:
DPA UA0896 -- smaller, VERY MUCH less effective than A81WS outdoors, but more effective than the stock pop-screens.
Shure A81WS -- larger, MUCH MORE effective than UA0896!!!
I personally run the DPA UA0896 indoors, the A81WS outdoors. The DPA UA0896 are NOT effective outdoors unless you have just a whisper of wind!!
I have had several outdoor recordings ruined by the ineffectiveness of the DPA UA0896 during windy conditions!!
