Very quickly done without using the undercut. A big span and hard cut loose. I also agree that 7b+ may be a little generous

Did it with old cheese along the lip. 7B seems more like it. Fun problem though!

Did it via conventional lip shuffling sequence rather than the undercut and slap way. Maybe only 7b this way. Still very good.
