I see de Boorder was standing up to the stumps for Duffy, Butler and Neesham yesterday.
Butler has looked quite sharp this season in the other video I have seen him in, including the televised T20 match. While Duffy looks like he is lacking rythym this season but I would guess is still sending them down in the 130s. I have only watched the wickets and boundaries via the front end, but that's pretty impressive keeping I am guessing.
Interesting blog I read recently about the value of a decent keeper (over a limited keeper that can bat/hit) in modern T20 cricket etc:
