Rightly said, don't mind countries prepare pace or spin pitches, but bounce has to be consistent.
Saffas made green tops to negate Herath and Faf was open about it. But you can't have a short pitched ball bouncing onto shoe height in cricket at any level let alone at international level. And yes, even 5th day of Test match is supposed to be played on a cricket pitch, not on ankle shooter strips.
To be fair to Aussies, they make the most neutral home pitches overall if you take the whole series into consideration. They provide teams with pace, spin, flat roads etc at various venues so good teams can really compete if they play well on some of the grounds if not on the one or two pacy grounds. Can't say that for the rest of the teams.
