@Buzz can I ask what grade bat you have please mate and your overall thoughts
I have a 2.11 libro club bat from two or three seasons ago. I bought it on ebay, so I don't know if it is an import or one for uk consumption. I paid around £80 for it.
It is a decent shape, nice pick up but has some graping which is very hard on the face. It is great for a net bat and bowling machine. It doesn't come close in performance to my BBs or my Keeley.
Could it open up more. Maybe, but I won't be holding my breath.
Is it a plank? No, it is ok but usually you get what you pay for.
I should add that I really like the bat (and the shape of the handle). I would guess it was made by sondhi or SG rather than SS though.
