I may be strange but I don't use dis dvor much if all all, I like relying on my cossack musketters once I get them to win battles,and for that I need decent pikes. so I usually hire some Landsknecht pikemen,as they are avaliable quite near my territory. Add some artillery to that,and against the poles/hungarians and there calv-heavy armies-I usually stand a good chance of winning battles,provided I choose my battlefield wisely and make sure they can't outflank me,or get behind my pikes,as by the time they get to my forces,there morale has been reduced by mass musketfire and artillery,to the point that they mostly rout as soon as they hit my pike-line.
