Hi,
The Hill bow would be a American Flat Bow with shelf, the Bickerstaffe bow would be an English Long Bow, I spoke with Pip and he said that would be his choice of woods if he was making the bow for himself, I could have more fancy woods if I wanted but if I want a bow that will do the job for years to come it would be with them woods.
I've had one of his bows a very long time ago and it was a great bow......Hhhhhmmmm
