The Noldor Spirit Horse is like riding a speeder bike in comparison - and far more feeble than your average heavy armoured warhorse.
Whut? Noldor Spirit Horses have more Armor than any other Horse except for the Netherworld Charger and the Demonic Charger (Or whatever the things Demonic Magnuses ride is called) They also have one of the best if not the best Charge and Mobility Values, More Base HP than most horses (180) and by far the best speed. Ofc, the Speed modifier can work against you as well but NSH are still far from feeble. And by far the best horse available. Trust me once you go NSH you never go back.
