Petrus user here, I main a Dayan Tengyun V2. Average is 14 seconds at the moment, want to be sub 8 eventually. Started seriously cubing in May 2019. Learning ZBLL if you’re interested. I use ChaoTimer and a Gen 4 stackmat. My cube collection consists of: Dayan Tengyun V2, Valk Power M, Weilong GTS2M, Aolong v2, Rubik’s Brand and MF4S. Hopefully it’ll grow.
