Which came first, the route names, or the crag name? Whatever way it happened it has to be said that the place is no more misty than any other Pembroke crag. It is rather compact and shiny though and also a huge sun-trap - get caught here in the wrong conditions and you'll find yourself slipping around on frictionless rock, above some tenuous microwire placements. Come when it is good though and you will find some great routes that tend to be more emotionally draining than butch and beefy.
The big tick for most is Bon Voyage (which does have a beefy crux) but equally good is its more direct variation Play Misty for Me. Once those are done there are plenty more lines in the E2 to E5 range.
