In reply to teddy jones: From checking the tags before I climb, and only bouldering to V3 (not very well) at mile end and the arch, at times it can seem slightly subjective to me. Routes are set by individuals with a higher skill and all round strength level im guessing to those especially to the lower grades. So a v2, for example, hold placement wise may seem easy enough, but to someone with less reach or less developed muscles, it will always be more of an effort. I do say this from the opinion of someone who admittedly has not done any courses and is predominantly self taught, so I agree on many levels my technique will not be as good. But trying a v2 at the arch, last week, which was upside down for at least two moves, before what appeared to me at least to be quite a stretch upwards, that after this long winded rant that may not have progressed this post any further, that sometimes no, the grades at the arch have been spot on for me, apart from the odd route.
