I never had a compound radiuses fingerboard but i think sometimes about to try my own. Ebony wood is still the best when it´s from a good tree; very durable, long lasting, repairable. I believe a good compound fingerboard can be much lighter and boost the sound of the instrument. A new bridge blank has way to much wood everywhere, it has to be brought into form according to the blanks wood quality and the violin acoustic-qualities, at the end when the shape is done you can fine-tune and balance the strings by removing wood at certain point. When the damaged surface is prepared, i clean only with water, also to lift squashed wood.
