I think Harris , Starc, Hilfenhaus and Lyon is a pretty good tail... Throw Pattinson and Siddle into the mix and I think that's pretty impressive
On the other hand, Broad has a test ton and 8 50s, Swann has 4/5 (not sure which), and Bresnan averages 40 in Test Cricket! I'd take them over the Aussie tail, although to be able to at least hold the bat at 11 must be nice, when we have Finn/Monty it all seems a bit Chris Martin, although if you play Bres Broad Swann Jimmy, it looks much better! SA do well too, Steyn/Morkel can bat, and Philander has a few FC tons. NZ get by as well, Chris Martin aside of course!
