Have no doubt that either will work , albeit a bit fought to carve 9 black locust ) .
The problem here is that the trees died some years ago . Black locust is tough , but that tree may be filled with rot from insects and/or checks from remaining in log form for so long . Black locust like to check when treated improperly .
Checking is of little concern with fence posts . I know because I have been installing fencing for over 40 years . I still tap Black locust posts if/when you can find them .
Bottom line is that you can't know what you have until you begin cutting and I wouldn't be waiting another day get started .
Assuming that you get some viable product , you will want to immediately seal endgrain and treat it like a freshly felled tree .
Good luck .
