Byrom just looks absolutely scrambled to me, he needs to be removed from the firing line. Last 2 innings have been characterised by a few sheepish prods , followed by a lunatic shot because he seemingly can't face being 0 off 5. I liked what I saw of Smale last year, places 0 value on his wicket and just goes at it from ball 1 with a clear mind. Only a very small sample but he actually reminded me a bit of will smeed. If we're going to take advantage of our long batting lineup I think our openers need to bat like that. Carlson has done it brilliantly so far up top, just need someone else there with him.
Other option would be to stick Marnus up top and play another bowler or allrounder. Billy Root has always done alright for us in T20 aswell
