We really should be playing 3 Tests against Zimbabwe but considering how Zimbabwe just wanted to start with 1 Test series, it's probably too much for them to host 3 Test series. Also I'd rather start with Tests 1st rather than other way around. Tests should have the most importance and therefore should start 1st.
Good news is that we play our T20I's and ODI's in Bulawayo but bad news is we play in Harare for the Tests. Bulawayo favors our style more. Should be a good contest. Won't be easy by any means.
