Our European hazel is a great bow wood for flatbows. Very flexible and elastic. No problem with frets.
I sooo beg to differ;-). Im from Denmark and have made bows from most woods available to me (elm, ash, plum, oak, rowan, cherry, blackthorn, hawthorn, yew and ofc. hazle)....Hazle has been the most troublesome with regards to fretting, by a margin. BUT also yielded my fastest shooters.
I prefer to think it a question of lack of skill and experience....hence my appreciation of guys like you who can pull it of:-)
Cheers
