actually the cash is ready for either B+W XS-PRO (RM290) or HOYA HD (RM250), the main concern is which filter is the best. Since price is not the main issue here, hope you guys can give your opinion on this.

B+W filters use brass rings, vs Hoya, which uses aluminum rings. Now, I will preface this that I am not sure about Hoya HD, as its new and there is no info on the Hoya website. However the Pro1 line is aluminum.
B+W uses brass because it is less susceptible to shrinking/growing in cold/hot weather, and won't bind to filter threads on a lens. This means that even if you put your filter on in a warm room and shoot in freezing temps, you can easily remove the filter when needed.
As for glass, B+W uses Schott glass, some of the best optical glass in the world. Is it better than Hoya? Who knows. Use the filter that works for you, that you can trust.
