Six day tests in the Winter?

Here's an interesting proposition, which Pakistan has turned down. Due to the early evenings in Pakistan in the winter, specially in Punjab where a lot of the test matches are currently being played due to security concerns, test matches are running out of time every day.

While a six-day test routine may have problems with scheduling etc., perhaps it would be easier if the PCB worked a little bit harder to convince international teams to play some of their cricket in Karachi and Hyderabad. Sindh has been abandoned by international cricket, even though Karachi has some of the most avid cricket fans in the world.
