Been comparing bowling records of the legends in Pakistan, McGrath at his best took 12 wickets in 3 tests at 28.66, Holding never played tests against Pakistan, Roberts took 12 wickets in 2 tests at 26.6, Marshall at his peak took 14 wickets from 3 tests at 16.5, but the pitches in 1986 must have been more conducive to pace bowling to what's been rolled out now. Cummins' 12 wickets at 22.5 is right up there in top 3 bowling performances from a touring side in Pakistan!
