Interesting stuff.
Maybe I was expecting a bit to much or maybe just got to give it some time.
The profile of the DS is not huge 35 mm edge with no concaving and minimal spine. Maybe there isn't enough wood present to have the bounce back I got from the other bat. The DS is on the left and the right is the Pakistani bat.

In that case, the Newbery Tour is a very poor design and will have a poor middle.

In terms of spine height to middle responsiveness, I would argue that the Tour is best, as a cricket ball makes contact with the bat over a circular area, rather than a pin point, so it's the mass of wood behind that area which counts! I would say give it a little time, I've sold on so many bats I didn't give time to play in properly, that I end up regretting the sales of.

How is your Aldred? I think I had a slight weight problem with my Aldred, but it was only by 0.5-1 ounce, which is fine. Maybe the working conditions at Paul's are slightly drier than our locations, so it picks up weight on the way. I know my Laver and GN Ashes have both put on about 1.5 and 1 ounce respectively! (GN did so over a period of 2 weeks!)
