So far, Niesch's R1 and Armani's R3 levels remain unsolved for me (at least the newest version for Armani, since I backrouted several of the previous versions). I was going to wait until I had solved them before posting my replays, but I'm not sure if I'll be able to get them solved before voting starts. I know it's not necessary to have them solved before it, but it would be nice if I can. I think I'll get them one of these days, though
However, I do have a working solution for eric's R1 level. In particular, it's a no disarmer solution, so definitely not the intended solution, but it still uses all skills. This one still took me a long time for me to find, though. Very fascinating that even with the disarmer pickup the solution still wasn't that obvious to me at all
I've watched the intended solution and I seriously cannot believe I never ever saw that route. Still, after a lot of struggling, I was finally able to solve it. Due to taking the old route, I was always 1 shimmier short. Managed to get around that by finding this solution.
