I am rather bemused how you can say that tiny dent, on the back of the bat, can have put you off it so much. Will it affect performance? no. Is it a massive dent or hole in the bat? no
It will be fine, it will pick up plenty of dinks throughout its life, as most bats do, so would you let that put you off? What happens when you edge one and it leaves a tiny surface crack? will it put you off?
Looks a lovely stick regardless, hint of GM with the stickers and colourway
