What advice was that?
Within reason pick a few bats in your range, then ignore the dead weight and get the one that picks up the best.
So if you use 2lb 9 for example pick 2lb 10/11, 2lb 8 or 7 etc....
And a well pressed grade 2 bat is equivalent for us club players as a grade 1.
Pressing is key and that goes back to Newbery when their bats were made by one or two of the best batmakers in the Country.
I don't know who makes Newbery bats now but whoever owned a decent grade one in the 80's, 90's..I'm not sure about after that...would know what I mean.
They were fantastic bats, hard to say for sure but they seemed pressed beautifully and picked up fantastically well.
My opinion only but I believed in that period you could not buy a better bat, I think it's a shame they are not the brand they were.
