I think roof climbing techniques are ignored by a lot of trad climbers. Sport climbing and bouldering tends to be more steep and you learn pretty quick how to conserve energy and create rests on roofs with body position.

Ie i found M.Times and Son of E O to be piss easy yet more techy stuff like Snookys and Birdland gave me a harder time.

practice.. road trip to Rumney or RRG to develop skills to lead on roofs with clean falls.
