He still probably won't make the A side unless McCullum decides he wants to go down the order as when Ryder returns he'll replace Ingram. Also, it's all well and good him playing well against Bangladesh but we'll wait until we face Australia. He'll be tested there for sure.
As for tests, I don't rate his technique, but look at some of the openers in world cricket these days - Sehwag, Gayle, Watson, Dilshan. They all play recklessly and get away with it because the pitches these days are just so flat. He's worth a shot purely because I like his intent. He doesn't let the bowlers jump all over him, he's always looking to dominate.
