I haven't had the pleasure of witnessing Bradman, Hobbs et al first hand, so I'll base mine on my lifetime of watching cricket (1990 onwards, basically).
Smith/Hayden/Cook (honestly can't split them), Sehwag, Sangakkara, Kallis, Tendulkar, Lara, Gilchrist (wk), Warne, Akram, McGrath, Muralithiran.
12th man: Waugh, Ambrose or Donald.
