Michael, thanks for a fine summit added! Your description arose my curiosity, so I found that on Hikr.org the north route is rated UIAA II and the route you did (from Ginzling) is called the normal ascent. So, your judgement is right, it's difficulty is either II or a bit less. And you should call it the southwest route, not south route, I guess.
Ah, most excellent, thanks Vid! Updated the page(s)...
