Add row command to just corn rows or to split rows also?

I plant roughly 1,000 acres of corn in 30” rows a year and 1,000 acres of beans in 15” rows a year, adding row command to my 1790. Trying to decide if it’s worth the extra money to add it to the split rows also. The row shut off will be used quite a bit as a lot of our fields have tree rows, rock piles, drainage ditches, and oddly shaped fields. Thanks!
