I had a Laver Carbo Firefly (Grade 1) long blade in 2'9/10
And also had exactly the same profile, weight and spec in Grade2/3 (Churchill) for a Net bat.
I sometimes try to match the net bat with match bat.
But most of the time, I actually just practice and test oout some of my bats.
Whereas other times, I try to use a heavier bat in the nets. I think this gets me used to using heavier bats for matches!
I used to use 2'9, but this has gone up to 2'13 as my match bat, and I am now timing and middling the balls better than I used to! So I think there are more than one method of improvement?
