Double Stroller Owners--HELP needed

[sillyguys]

What kind of sun shade do you use for your double stroller? I have a Valco twin runabout and last year we used a sun shade from rayshade (I think). The problem was that the shade flipped up easily in the wind and we often found ourselves pushing the stroller with one hand and using the other hand to keep the sun shade down. I was wondering what type of sun shades the other double stroller owners have used. Thanks.
