I believe red oak does not have the typical ability to recover it's size and shape after being stretched as much as other woods. I believe that this can be remedied by backing with a springy backing, like sinew, which would have a much higher resilience than the bare wood. Other than that obviously well known problem, I haven't got chrysals in red oak yet. All my linen backed red oak bows shoot way better than the unbacked ones. So I see no reason really why red oak cannot make very good performing bows.
