Adjusted drush into Castle with Viking?

Hello you awesome peeps, recently started playing Aoe2:De, needed some of that childhood nostalgia.

I been trying to learn Vikings cause I am from Norway, obv. And I saw Hera say that Drush into Castle is the way to go, but I was wondering if I should do normal Drush into Castle like other civs would, or if I should try to get Feudal earlier then other civs cause of the free Handwagon? Any help would be greatly appreciated.

Thanks
