As I know that CricCounty have been to the SG factory in Meerut and purchased a huge stock of their bats and some of those bats were intended for some of their sponsored players, it is only an assumption that it is graded as pro, whether it is or not, it is still a nice bat with a decent ping; I am not too fussed on the grading of the willow; as it is not all about that. As I have provided some business to CricCounty along with carrying out works for them, I was given a great deal; I was not looking for a new bat, but I am hoping that I can use more next season as I hardly bat this season and when I did for my club, I never got out in the 9 innings.
And that’s my point there is no “pro” grade. Just means people pay more for nicer looking G1 bats is all.
Just my view and as you say looks a nice stick and most SG’s I’ve used and seen have been decent bats albeit narrow and the normal tricks to reduce weight vs size but hope it scores you lots and you enjoy it.
