I have 4 staves with plenty of length, fairly straight and no knots, all 4 are white ash, cut by me 2 summers ago, 2 with bark on and 2 with bark off - all 4 were and are being stored outside. The 2 with bark off are a little discolored - not sure about them - the 2 bark on staves I think are great - as it was 3 with bark on not too long ago and the 3rd made fairly nice bow - although not war bow length or poundage.
If you want some pics, let me know. I am sure if you are interested, we would work out a trade.
