It's been quite a while since I did the ridge between LD-007 and LD-010, but my memory of it is that it was not at all challenging. You can get a perhaps better feeling for the "lay of the land" from the sotamaps page than might be suggested by the contour lines alone, by clicking on one or the other of the summit markers for those peaks, and clicking on the "Panorama" button in the summit marker popup window. We are lucky in that, in both cases here, the panorama window shows the view from the summits themselves so that, with a bit of judicious panning and zooming, we can see the view from one summit to the other, and vice-versa, and hence see much of the route from one to the other.
The views are admittedly not of the best quality, and you can no doubt find better online, but such views can often be helpful to make a quick, provisional appraisal of an area of interest. Here are two examples taken directly from the mapping main page, to show what such panorama views can offer:
This is the view southwest from St. Sunday Crag toward Fairfield, where the path ascending Fairfield (rather indistinct here) follows the obvious broad ridge in the center of the photo for most of the way up, then trends out rightward over easier ground.
This is the view back the other way, from Fairfield to St. Sunday Crag, where the "razor"-like ridge reveals itself to be a gentle bumble up/down a whale-back
The panorama window can also be resized by use of its' "Window resize" button.
The suggestion of LD-005 with LD-014 from Seathwaite/Honister BTW is very well worth following up - these two are among the grandest of the English mountains, with phenomenal views all round. Be advised, though, that Seathwaite/Seathwaite Fell was awarded the title of "wettest place with rainfall statistics in England" so pick a dry day for your activation.
Another idea for LD-005 and LD-014, if you're feeling fit, and taking in LD-006 as a bonus, is to do a "horseshoe" route, starting from Wasdale Head, where you can camp or take a room at the hotel if you're lucky. Start at the southernmost end of Yewbarrow Fell, traverse Red Pike and Black Crag to reach Pillar LD-006 halfway round. Then on to do LD-014 and finally LD-005. Back to the col between LD-014 and LD-005, and the steep but easy path back to rest and refreshments. A really grand tour, taking in three great peaks: just don't do it at the weekend!
