The final stance is actually where the blue dashed line begins (refer to topo). There is a ledge at this level.
The final pitch follows this ledge (traverse right, facing the wall), aiming for the offwidth in the corner.
Once at the offwidth, it is possible to pull up and step right onto the final headwall. From here, the route goes pretty much straight up, stepping right at one point to avoid a small roof (refer to the photo I posted).
It is also probably worth mentioning that the route can be followed back down via a few (I think 3) abseils. Whilst climbing the route, you will notice the odd ab-station here and there (bring your own ab-tat). This is a quick descent and way more convenient than walking all the way back down. The final ab is the same one used for Crackattack, and will land you right back at the start of the route, so you can leave your approach shoes and excess gear behind
