Pleased to see Compton get a candle. Think he'll add ballst to the middle order.
Still don't think it's 100% Root will open, both Trott and Bell have done it before and, as he's already played over a dozen tests, it makes no sense to take Eoin along for the experience, so one assumes he'll play. I guess that makes the sixth spot a straight choice between Compton and Root. Would prefer the former myself, although the latter's offies may tip the scales towards the young tyke.
Will we play two spinners? I'd imagine so, which does raise the four man or five man attack spectre. If it's the latter you'd think it'll be Sammy at seven with three seamers; the former Monty with two & Trott (

) as first change.
