If there was a skid steer on site I definitely would have leaned toward bombing it out but speedline seemed like a good option to save labor,on a rope is on a rope,it didn't look like he adjusted sizes of the pieces being cut very much.could have even taken longer lowering to the base and waiting for guys to process and clear the area,just my thoughts.
I was thinking the same as you initially but that's what I concluded lol. Also the video would not have been nearly as good
