Am I required to use 2 Crimson Rites to have both ends of a polearm apply damage?

First, congrats on the new force grey! Second, am i required to use 2 crimson rites to have both ends of a polearm apply dmg?Thanks! And Just as you would need two rites to apply to an offhand weapon, you need a rite for each end of the polearm (for balancing)
