Personally Id be worried with buying so many dowels. take into consideration grain runnoff spine and many other things and you will potentially have 20-30% good dowels and the rest crap. best case scenerio 40% which may be good but not guaranteed spine. The reason I tell ya is because I checked out the packs of dowels at lowes, homedepo and at the lumberyard and found this to be the case, so perhaps think twice. Plus bad dowels can cause an arrow to break and go through your hand, so just my two cents. on the other hand if they turn out good then you are set.
