In reply to OliBangbala:
I disagree with what seems to be general thrust of the advice on this thread - ie. that you should sack off redpointing and focus on getting onsight mileage.
If your goal is to climb 7a, then you need to be doing the sort of moves that you will find on a 7a. Climbing lots of 6b and 6b+ will get you very good at climbing 6b and 6b+, and long term is going to be essential to you developing as a climber, but there is no reason why you shouldn't learn to redpoint at this stage. Yes you will have a lot of work to do in the future, going back and filling in the gaps, but doing your first 7 is a big boost to the psyche.
That being said there is a real art to redpointing stuff properly at your limit, and i would not recommend you get on something 4 or 5 grades harder than your current personal best, as your first ever redpoint project. If you have 2 weeks, I would spend the first week learning to redpoint - doing some fast (1 day, probably) ascents of 6b+s and 6cs - take the time to really learn the process. Get a benchmark for the hardest thing you can do in a day - really you want to be able to get 6c in a day and 6b+ within 3 goes or so to stand a chance on a 7a. Then pick something inspiring at the start of your 2nd week and really go for it.
FWIW When I did my first 7a I had not done 6c+ and had only done one very soft 6c (more like 6b+), which I did onsight. I was fairly routinely onsighting 6b with the odd 6b+ on a very good day.
Be prepared to fail. Coming back from a holiday having spent a week on one route and having failed to tick it is gutting, but is part of the game of redpointing.
Also I thought Poema de Roca was shit, over-hyped, really not that easy for 7a, and has people queueing for it all day as everyone climbing in that cave uses it as their warm up - I personally find it a bit distracting when you are thrashing around on something at your limit, to have a queue of people forming tapping their feet and waiting for you to be done.
Cono Paco at sector Suiza is fairly amenable at 7a - bouldery crux low down, then a good rest, then hold it together to the top. If you are a boulderer at heart and like the steep, Cosas Caseras at Desplomilandia, is in the guidebook at 7a+ but in reality is 7a and probably not a bad shout if you are fairly tall.
Get in touch with biscuit off here, he lives out there and will be able to point you at 7as.
