I'd actually be more than happy with day-night Test matches.
As far as I see it, they'd need to be played with a white ball (or, more likely, a series of white balls), which means we'll lose some old skills, such as bowling with a new ball or an old ball.
But we've already lost the skills of bowling or batting on wet wickets and sticky wickets, so these things happen.
Tigers vs England as a day/night series ? Bring it. But, please, volunteer to play three day/night games against England A sides first.
Oh, and Tour Ireland First. They deserve a months worth of solid cricket
