Thanks for the info...
I was sure i'd seen the direct ascent on Fairfield in the Wainwright guides... in fact a quick check and it's shown in the Hart Crag chapter... up to head of valley then climb straight to Hart Crag-Fairfield col, or Dove-Hart Crag col... as you suggest, it does say it's steep going!
Did something vaguely similar in the Mountain Trial a couple of years back. Dropped from Alcock Tarn/Heron Pike into the valley, along half a mile, then a beeline ascent straight onto Dove Crag... can confirm it wasn't much fun!
I do like the odd direct ascent like this... if you can climb reasonably, they can be useful... Mickleden straight up the scree and Axe Factory to Pike O' Stickle... Levers Water straight up to Levers Hause... Grasmoor via Red Gill... and so forth
