I was just gifted a set of double staff and I'm stoked! Been watching your poi tutorials since I started poi but I didn't know you spin double staff too :D
you first demonstrated the split ops as point isolations, but at the end you switched to split ops of horizontal line isolation a.k.a antispin split ops, which is more advanced I guess than you planned to do in this tutorial. this happend because the switch to split-ops was on the horizontal, not the top-bottom switch as for the point isolation.
