Heya, I climbed years and years ago, and cant wait to get back into things again, mainly bouldering and doing it solo, any advice? Also I dont understand the grading difficulty? As forgot everything I learned lol I found some nice routes, is there something I can download or buy to see the exact routes for bouldering, like tells u where to start and where to go and finish etc? Cheers 

There was a kid on here called Cneifion Arete - he'd be good for you to talk to. Or not.

I recommend this guide as a starting point:

 then get a bouldering guide for your local area with photos of routes.
