You have to spray the bark on your staves with a strong bug killer or wood wasp larva and powder post beetles will ruin your wood QUICKLY!
In my opinion you cut way too many trees to handle in a reasonable length of time and are going to loose a lot of your wood to bugs and checking. You would have been better off to cut one tree, work up all the staves, the number of staves from a 20" tree will be substantial, then move on to the next one.
At 70 years old and after 20 years of bow building I now have a monster case of carpel tunnel syndrome to remind me of all that draw knifing.
Make your first split in these big logs with with a chainsaw, it will take you an hour or more or of heavy pounding on wedges to halve them, save your strength, you are going to need it.
Been there done that, I cut too much one time and spent a month debarking and removing sapwood in my spare time and on my days off. My hands swelled up like sausages from all the drawknife work, I still lost a bunch off wood because I couldn't work it all up. I think I cut 5 big trees, it was too much.
I don't know how many trees I have cut in my lifetime or how many staves I have worked up, over 200 staves for sure, probably less than 300. I have made over 150 shooter osage bows, ruined a bunch of bows as well as staves and given away countless osage staves.
I recommend you remove the bark and sapwood while your wood is green, this way you will not have a bug problem as the larva are in the bark. If the bark goes you have to take off the sapwood as well or your staves will check from back to belly. I learned this the hard way, in Alabama no amount of sealer on a sapwood back will prevent deep checking.
I still have a few staves in reserve for my old age;
A few billets as well;
