Followed this thread with interest this weekend.
Fwiw, Glaciated Slabs was absolutely lovely. Bit slim for anchors and the approach up scree/boulders is indeed horrible, but the climbing and views were lovely and just what we were after for getting more used to Lakeland rock. Some lovely routes.
Went to Upper Seathwaite Slabs on the second day and was very different (though again, lovely views, and things were a bit harder in the rain). Very slabby, definitely, but absolutely negligible gear, particularly on the long Mod (Smoot Sethera-?). One section seemed to have about 10m of runout, including on a traverse; have to go a good way back to build an anchor and almost ran out of rope with a 60m (actual route took more like 35m); on one of the Diffs, too (Tan?), my partner only found one piece. Nice climbing, and know it's not my accustomed rock, but felt weird that a Mod at least had so little protection. Wouldn't recommend for new leaders unless they're happy basically soloing...
(If, actually, the FRCC guide is wrong - their diagram had the route not following the obvious cracks, which would have made it much easier - the very start move was terrifying! - would be good to know... can't find any feedback elsewhere.)
