frankly I just find it unrealistic that Fate and Nanoha could match Wolkies even with cartridges. Experience is a HUGE factor, someone with as much combat experience as Wolkies shouldn't loose to a couple of amateur kids.
The Wolkenritter do not have a single attack that inflicts magical damage. Signum conjures real fire. Vita hurls metal bullets. Even without magic, their weapons are a sword and warhammer which can gouge and crush.
The only Capture-type spell that Zafira has ever shown conjures blades that hold the target in place by STABBING them.
Further, their centuries of experience have conditioned them to cripple, maim and kill. Not only do they lack experience with defeating foes with a minimum of permanent injury, they have to actively FIGHT their own reflexes to leave Nanoha and Fate alive.
On top of that, the Wolkenritter are not as motivated to fight Nanoha and Fate as the kids are motivated to fight them. The Wolkenritter want to save Hayate, but they don't want to kill these kids to do it.
Nanoha and Fate don't have to worry about killing the Wolkenritter, because their magic and fighting styles are generally non-lethal even at full power. They can put their whole heart into attacking without hestitation or holding back.
I'll also note that Nanoha and Fate never actually beat Signum or Vita (that was the twins at work). The girls surprised the knights with new capabilities after the upgrade, but that doesn't mean that Signum and Vita wouldn't have adapted and turned the tables again.
