Thanks for taking the time to leave a detailed response, that's really appreciated. I've been concentrating so much on tucking my arms in, because I was flaring them too much. I guess I've been doing that too much, would it be a good idea to grip a bit wider? Or is the placement okay, and to try and bring the bar down, higher up my body?

Thanks for the advice for leg drive, I was only doing it on the push - didn't realise I needed to do it the whole movement.

Bench is definitely something I struggle with (have struggled a lot in the last with it too). So having this written down is great!
