Its always hard to tell before it’s boiled as weight / volume are very critical.
However it should have good scores across the board, therefore I think 150 is going to be a pretty good guess. A client had one from April that was 149.3 and this is a very similar head although colouring is better and the head is likely to weigh more at this time of year, however that could cause the volume score to be a little lower. As the head in April would have been more porous.
I will have it provisionally done over the next month or so, After a couple of weeks of drying it won’t lose much more weight so you get a pretty good idea.
