I've had a bat that was genuinely destined for a pro. The grains looked lovely and was gorgeous... I sold it..
- Just because its a pro bat, it wasn't made for you (unless it is exactly what you wanted
) so from the off you may not get on with it
- Sometimes pros adjust their shape etc.. for certain tours so again what kind of wicket are you playing on...
- As people have mentioned pros could bat with a grade 4 and still get runs...
If you are fussy I'd suggest the custom route and gets something made up for you... unless you can pick it up and feel you are going to get on with it I wouldn't personally bother...
... but as always do what makes you happy
