I've been there twice sport climbing and thoroughly enjoyed it.
The bolts have all seemed fine to me, I remember reading an old Climber article where they were talking about having an appropriate standard for sea-cliff bolting there. At any rate I have never felt worried about the bolts and I'm a complete coward.
Similarly with the rock, I've had no problems with stability at all. There can occasionally be a slight sandy feel to the rock, but no worse than any other normal sandstone (i.e. not SS). Obviously it's worth avoiding after the rain.
The climbing is cool, technical, and interesting, and there are quite a few good routes in the 6/7s (I've only done stuff in the low-mid 6s, which were good). Certainly a refreshing change from limestone - have a look at the photo of Elysium in the Lakes selected guide!
