Eh, given that Cartwright is the fourth and is very much a batting all-rounder...I doubt many recent touring squads to Asia have more than 4 seamers at all tbh
I'd be taking four specialist quicks -- from the point of view that this really locks Australia into the 2/2 attack make-up; if you pick all three in the first Test because there's a hint of green and Cummins breaks down, all of a sudden you're flying Behrendorff (or whoever) across anyway.
