I do use cantabrian circle a lot, and it works well for me.
If you order each HA unit to attack a target, they will start circling as soon as they start to shoot at that target. It makes a big difference (less losses). Even standard unarmoured HAs can withstand arrow fire for quite some time while circling.

but there main task should be to shoot arrows at the enemy, rest if possible an then follow the charging FM cavalry to finish of any enemy forces remaining. Differently from other HAs they can fight quite well in meele especially if there used to charge alreday engaged troops.
I often use Saka Riders for this job. Albeit not armour-piercing, their lances are faster than those of ESN, they are probably as fast as any infantry weapon, so they do quite well, too. (+ they are cheaper)
