Looking for topo's for Alpspitze and Zugspitze (German alps)

I've done the Ferrata routes on Alpspitze and Zugspitze and am now looking for a more exciting way to the summit! The problem is that there isn't much info about the other routes up these mountains. The only thing I can find is the Via Ferrata routes. They are fun but I need a challenge! Any help would be greatly appreciated.

Also, if anyone wants to climb late September, early October, my friends and I will be attempting some autumn climbing down there. We will wing it if we can't find detailed topo's lol. That'll be a real adventure!

Have you checked out the Jubilaeumsgrat?
