rh,
Whatever makes you happy. (of course your 500 is the best machine to whip the empty hook around in, but what's the point with that?? It's the load that counts!!) The original discussion was what to use for lifting when the 500
couldn't do the job, and the gentleman was asking for the 600's suitability.
Delta,
You can check this list:
AeroBoek Index which list all MD's made(and some other types). Browse through it and see how many of the respective machines you ask about is used for lifting.
FP,
Couldn't agree more
