In reply to SulkySubset:
There isn't much to it, it's just playing on rocks. I think you are over-thinking it. There never used to be much info about 'how to boulder' since it is basically, absolutely obvious. I'm not a oldie who thinks are mats are for modern pussies, I am proud to be part of 'generation pad'.
Best beginners venue is Burbage South, Cratcliff is good too, Roaches not bad. Your research is clearly excellent!
I don't have any of the new bouldering guides so can't recommend one. If you think you're likely to climb trad in the future, I would start collecting the BMC guides to the Peak because they're brilliant guidebooks - but from a practical point of view I'm sure the new Rockfax will be good too (plus there is a picture of me in it, apparently, so that's a good reason to buy it).
You might be surprised about how hard the grades seem at first. The thing is that on gritstone, the climbing involves very different skills to indoors, as it relies a lot on friction. Topping out can baffle the beginner who is used to grabbing a jug and then jumping off. Once you have some experience you'll realise that it's not a conspiracy or a rip-off.
If you think: if I fall off that I'll break my legs (which is quite often the case, but not at Burbage South Boulders) then you don't have to climb it. Some of the problems in bouldering guidebooks are 25ft high with atrocious landings, and get E-grades in other books. This can be alarming at first.
Good luck.
