In reply to Jon Stewart:
It's true that cams are useful on gritstone, sure. I have invested in 6 or 7 over the last 10 years, and happily place them in parallel-sided cracks, where nothing else will fit. And there are plenty of routes on grit that I wouldn't attempt without them.
But I wouldn't go out and spend £200-300 on cams before my first visit to the peak district, which is what a few of you seem to be suggesting the OP should do. Fine, if he's got that sort of money, but there is plenty you can go at with a non-gritstone rack.

> But suggesting that if you want to enjoy climbing grit, you'll want a few mid-sized cams, is completely sensible. I suspect there is a hint of both 'hex-user self-righteousness' (something seemingly rife in the climbing community and as yet unexplained) and an inexperience on gritstone underlying your post.
I've climbed a few hundred routes on gritstone. And I am an advocate of hexes in general, because a well-placed hex is as good as it gets, and substantially cheaper than a cam.
