As you see in the photo attached there is a huge dent at the bottom of the surfboard's nose. This was created by hitting the rail of another surfboard when we crashed

I took it to a professional shaper in Bali and he told me that it is better not to repair it because it will gain more weight on one side of the board and it will affect the performance of the board. I was thinking that this dent will also affect the waterflow of the bottom channel of the board and maybe this is even worst. They also told me that there is a way to repair it with very light materials based on microfibers. I am confused.
Any opinions?
To be honest, i hate to see my board like this

I prefer to fix it and paint it.
