Good...You'll like them.They are very tough shafts compare to split timer shafts.Remember to prestraighten them every other day or every 3 to 4 days.Then rebundle them all the while in between[I use bale twine length or rubber bands or zip ties].Most times I bundle them butt to tip every other one in bundle.
Picture of straightener used for stiff end areas.I wear gloves straightening most times as shaft is very hot.
Eventually you'll see the bark begin to shrink.That'll take at least a month though.Bark can be removed also to hurry up drying if shafts are long enough [36"] to cut off any checking.You can seal ends if you want but I have never needed to.It won't be much anyway.I had a couple multiflora rose check length wise after bark removal,but not any dogwood though.
Trick for less work is to harvest them very close to diameter that you want for less work,but eventually most can be made into useable shafts.The final weeding process for keepers is shown when you shoot them.
