Hey Leonardo,

I personally found that all calvary armies worked very well against the Turks in the field. To prevent missile casualties you have to quickly get into melee with the enemy. Your knights (Hosplitars and Knights of Edassa) can easily smash Turkish lines with ease, even their spearmen in a frontal charge. Take three or four unites of mounted sergeants to take down their horse archers and have the rest of the stack consist of heavy knights. You could even use some of those mounted sergeants for flanking to cause the Turkish line to route. You will still take some loses from arrow fire, but they will be lessend because of the speed of your calvary. This worked very well for me in my campaign, although my mounted sergeants need to be retrain after almost every battle.
