Folks you never stop learning in this habitat game we play ..not an expert by any means but I do have some "earned lessons" that at the very least might get you thinking and do a bit more research as we still have time to do that research ..
1. You need to define EACH parameter of your Sorghum/milo's mission to really get effective result ..
2. Tannin content, maturity length, stalk standability, height and seed vs silage( do you want seed heads or plant mass?)
3. If you want random plants throughout for vine support but not really looking for as much seed contribution then a silage Sorghum might be you
4. If you want a seed source for later in the fall winter you will want a high Tannin variety with standability (deer won't eat high Tannin milo until winter hungry)
5. Color does not determine Tannin content but a lot of USA developed Sorghum/milo seed has had a lot of the Tannin genetically bread out of it
6. There is Sorghum/milo seed that IS TREATED to allow PRE-EMERGENT Bicep or Dual applications for those of you with grass and broad-leaf problems
7. If you want the Sorghum to be an early fall food source there are Sorghum seeds available that are zero Tannin and the deer and birds will strip them by October ..which is not a bad plan IF you have other forages within the area to continue the deer's feeding pattern
We use Milo not as vine support but as late fall/winter emergency food source as well as a means to "break up" more open clover fields by planting it in strips much like a farmer would plant a regular row crop of milo except we have curves n boundaries with open places scattered through out..
We archery hunt it as well as gun so we limit our variety of seed to 45" stated plant height shooting from 10' elevation
The deer seem to be much more comfortable with the "feel" that the 8' and 16' row wide "Milo break ups" offers them .. they even bed in the stuff
Good Luck all this season and be safe out there
