I agree with the above. Even the domestic white geese have such a tight web and oily feather that they don't dye well.
To get a good match and more visibilty if that is what you want - try to find some domestic whites and use them as cock or hen as you choose for contrast.
In general, I love the performance of goose feather. The only thing better is Peacock wing - and they are even harder to get.
Domestic turkey is the standard due to supply and demand - but they are not the 'top of the line'
Also as was said, I would be inclined to use a bright crown dip if visibilty in flight was the issue.
I am an old bugger and set in my ways so I don't like wraps worth a hoot! Same reason I don't use die cuts - only full length burned.
