My bow of 15 years now is a W. (which I think stands for "Wilhelm") Seifert, French model.
Round Pernambuco stick, ebony frog, mother-of-pearl inlays in said frog, leather and nickel-silver wrap (which now looks like copper, due to 15 years of the sweat from my hands).
Everyone I let handle it has commented that it is a pretty beefy stick, and a touch tip-heavy. But, I find that feature a pleasant attribute in a stick primarily used for Orchestra duty, since it lets me get some genuine attack (if need be) on an up-bow.
I've tried a few others, including some pricier ones, but I keep coming back to it.
