Yo man, I went to Suirana in December last year and it was damn cold! Snow on the ground, daily fog, rain and freezing winds, not ideal but we did do a fair bit. Of the stuff around that grade that we did, I would recommend the following - the sectors are all v close to the campsite/ refuge:
L'Olla
Guate aqui hay tomate 7a - a nice slab excursion with a testing crux at the top (where it should be)
Valga'm deu quin patir 7a+ - a nice pockety steep wall with some fierce moves
Primavera
Mandragora to first loweroff 7b - can you raise the bar by one grade? If so, this will rock your world, a pumpfest of the highest order up gorgeous orange streak
Remena nena 7a+ - looks excellent wall climbing; we didn't do this one but its a classic!
Village Crags
If you are stuck on a rainy day, this stays dry.
Remulo y Romo 7a - a nice pumper with a reachy initial crux off a pocket
May thing song ales zinc and punk 7a - a toughie at the grade with an improbable finishing roof!!
Pizza de pinya 7a - looks excellent, worth ticking even if on the way back from Campi qui Puigi.
Hostia 7b - if you can cope with 7b, this is a great sustained outing, knocking on the door of 7b+! Maybe one for the end of the trip?
Campi Qui Puigi
Toca-me-la sam 6c+ - a technical tricky number with numerous blind alleys, prepare to queue or go early
Tasta 7a - next to the above, much harder and funky finish
Delicatessen 7a+ the motherlode, we didn't do this but did the 7b+ to its right, looks mega!
If you buy the local topo when ur there from the campsite bar you won't go far wrong. There are other sectors that I never went to like Montsant, El Falco, Suiranella and Arboli which will have a shed load of low sevens. I think Suiranella in particular has some slabbier numbers. Have a good one!
