Cameroo, if this is still available (and it is exquisite), I have a reasonably straight osage belly sister stave that will be borer free. Here's a picture of that stave, it is the one on the right in this picture. The stave is 7' long so the crooked ends can be removed. That stave in the center has very nice reflex on the near end, but it will have borers in it. The one on the left is nice and straight, but there's a check in it that one that I don't like. I have lots of other staves, but none quite as straight as these. I also have quite a bit of sinew, 5 Texas deer worth from last year, both back strap and leg. Admittedly, they are smaller than northern deer and so is the sinew.
