I voted for the status quo. I think an unintended effect of Pakistan's, er, issues
with Hair is that it may've saved Tres's bacon. If Colly had gone on to make a big ton Banger could've (IMHO) been the one to make way for Sir Fred's return. As it is (& I realise Fred's fitness can't be taken for granted) I suspect Colly may make way. Not my call, I'd drop Bell, but I think that's the way the selectors will go.
Then again we might just say balls to it
& go with seven batters!
