It doesn't look a huge bat for the weight, considering it's a shorter blade!
However, as I know his skill as a bat maker, I would dare say that the bat will perform just as well as his normal level of bats!
But as great as James is, I would still go for UK made T20 bat instead.
The cost would be one issue - as someone rightly stated that Scats and Lavers work out very expensive at the moment (due to the currency rates!) another issue would be because I know how decent the likes of the Black Cat Joker, or the SAF Audax bats are!
One of these days I may just be tempted to do a T20 bat comparison!! That would be fun!
