I think I read somewhere that Whiley did a pretty good job on Pendlebury when he was given a tagging role so maybe he is an option for the bigger guys.Curnow is great for the medium sized inside mids like Ablett and Cotchin.
He can also do a great job on the outside runners but Curnow doesn't have the strength to stop a Watson, Fyfe or Pendlebury unfortunately.
