Yep, a big fan of the SQ 611 Active, I’ve used them based on your recco on both the urban and mtb.
Had to switch it up due to a bruised tailbone. That bump up in the back of the SQ saddle was an issue when dropping the saddle. I also get some saddle sores maybe from the firmness, and wider nose, of the 611.
This is the only Fabric saddle that comes close to working for me. It looks funny, but is brilliant.
