I propose we use '75' (as already) as a header - length (studs). As far as I'm aware all flex released has approximated an integer number of studs. Please correct me if I'm wrong.
so current 75 would be renamed 75-6. Probably 75 itself could be used as a shortcut to 75-6 since it's a pretty common short length
