From a lifetime of dolly landings. From R22 to B212. Dolly's take skill, but they are the norm here, you do them with everything for your whole career. You've got to learn your references, and be able to lift without drift in any wind, and land the same way, looking straight down. Any doubt, land on the ground. Would I try it on an unchocked dolly? Sure, done that, but again a higher skill level required because you can't drop it on misaligned and then try to slide it into position.
From all the videos, this pilot had no idea where the dolly was when he dumped the pole. Two things wrong right there. Dolly wasn't moving and he banged the skids center on the aft edge. That's a long ways off.
Nothing wrong with the helicopter, nothing wrong with the dolly. Man's gotta know his limitations.
