If you are going to try Lightning Strike, Relativity 7A next to it is good as well. Small moves through the roof. The only possible move that might be a bit reachy is going up after getting both hands on the face. But I have a vague recollection of there being an intermediate hold that I chose not to use.
Slightly out of the grade range but I thought Tension Set 7C+ was really good. Powerful moves out of the roof with feet quite close in and an undercut that might suit a shorter person.
I would stay off Stay Off the Weed 7A+ unless she can do it quickly. The block on the left kind of spoils it, I used feet that were quite far away and the crimp is hatefully sharp.
