Have you owned a lot of Newbery's? Does a bat need 40mm edges and a 70mm spine to perform?
No, I have not owned one Newbery as they have never appealed to me, I have had bats made by the same people as them. The TT was probably the bat that I liked the most out of the Newbery range however from my personal opinion they could have been made using a better choice of willow.
Bigger brands will have a selection of willow, of which some is used for the top end range and some for the bottom end range etc - not only grades, but weights of the blades and instead of using some of the normal weight willow for the TT's, it seems they have used the heavier willow, as one would assume that with the TT shape(it a T20 style bat), it would look bigger than other bats in the Newbery range that are SH as there is less height on the blade - the many TT's I have seen have looked very underwhelming.
No, I am not one of those advocates - however having been in the cricket business myself, there are things they could have done better with this bat to make it more appealing. Pretty much every TT that I have picked up in stores around the country, I have just as quickly dismissed it due to the poor willow that has been used - let alone some of them feeling very poor on the pick up, however there is the odd gem as there are with every model/grade/bat out there of which I hope yours is.
