You're much better off getting a specialist T20 bat, could save money and defo save you effort. Maybe a custom T20 bat with custom stickers at a discounted price to forum users?
I had thought about this so will more than likely do a little sanding on the back of the toe but not alot.
In an ideal world this would be the case but as I doubt I will find a custom bat in my price range, this is going to be my 2nd bat so only want to spend about £110 on it.
Bear in mind, you shift the middle down by an inch and you'll make the toe area thick so you end up having to re-do a lot of it.
Thats not to much of an issue as it will add to the weight reduction even if it is a little I sand off.
I'm pretty sure you'll be affecting bats pickup when you cut off handle as you're taking mass out of handle
I will be holding the bat up against the shoulder so dont think it will have to much of an effect.
