Noticed there’s two Siurana guidebooks published in 2023. 
which is the best one for routes graded up to mid 7’s?
I already have a Margalef guidebook

I've always used the Tarragona guide when in the area, it covers all the major Siurana crags plus other nearby areas like Arboli (El Falco is a must for long routes in high 6s to mid. 7s) and Montsant. Also has decent selected coverage of Margalef but sounds like you don't need that.

The one with the photo of the hand on the cover.
