bolds in de uk zijn blijkbaar geen garantie voor een relaxe klim.

SAFE but technical: Particularly hard, tricky and/or blind moves, relatively close to reliable gear or the ground, or between spaced gear if there is a good fall-out zone and little chance of hitting the deck. Failure to complete easier moves on these climbs may still result in injury. That's gritstone for you. e.g. White Wall (E5 6b), Millstone
SAFE but sustained: Good spaced gear or relative closeness of the ground, but the grade derived from the strenuousness of the effort required or very sustained sequence of moves (e.g. intense slab or arete climbing). Again, no guarentee that you won't hurt yourself apres crux. e.g. London Wall (E5 6a), Millstone
BOLD and technical: As most UK climbers who are familiar with the nuances of the British grading system know, these climbs can be anything from a few tricky moves above an ankle or leg breaking landing (with no gear), to one particularly desperate move above a back-breaking landing (with no gear). Suspect gear protected routes (e.g. the pegs used on The Braille Trail) come under this or the following catagory. e.g. White Wand (E5 6a), Stanage
BOLD and sustained: An sustained sequence of moves (whether steep and pumpy or intense friction section) above an injury guarenteed landing.
e.g. Hairless Heart (E5 5c), Froggatt
