Yeah I love these guys... and I've been trying to find a nice sized one since I lost my old one. They're always a nice centerpiece for any tank.
From the naked eye, I can't really tell the difference between the tyree leather and the ORA leather...but I'm sure there'll be arguments of lineage to follow if we go in depth. Only noticable difference would be that the tyree leather gets longer stalks, whereas the ORA ones stay wide and stout, but not a definitive observation since I've never had the chance to put them side to side.
