In reply to An Triubhas:
If you're planning on Jack's Rake, do it via a boulder hop up Stickle Ghyll (as recommended above) and then traverse right onto Tarn Crag and take in one of the scrambles there. Plenty to go at. Classic route is The Groove at III, but the lines on the right rib are also worth a look at an easy II ish. You can then top out, drop down to Stickle Tarn and then do the Rake.
Makes for a more interesting day out and definitely possible in a long half day.
