There's also the netting with wood fibers woven through it and that is what I used as that was what the farm service I went to carried.

I would use a 25% rye mix either way on any incline initially ( Scotts/walmart) then reseed next season.
Make sure to stretch the erriosion blanket tight when you staple it in place or your mower will catch it .
There is 6" & 4" staples , the 6" hold better
I had 220 yards of dirt brought in with about half on inclines .
The blankets worked fantastic and I only lost a couple of yards with torrential rains.
I also put in a 45 degree incline 8' x 80' leading to a "sunken patio" that is planted in seedum & ect. , the blanket works great even under this extreme angle.
