As above really. Should I be lookin for deeper grooves or sharp points in the teeth? For instance how much life is left in this cog? Just wonderin if it's finally time to replace my cassette. What do you guys think?

The best way I know of finding out is to put a new chain on and push some big gears. It will let you know if it needs a new cassette.

When the chain starts slipping quite a lot under power, then I know it's time to change things.
