In reply to Donnie:
On Saturday the upper 150m of the standard route up north ridge of the Loch Earn Ben Vorlich had complete snow cover and was very icy - good cramponing terrain. Not for the first time we met several people who had tried to get up it in such conditions without crampons or axe. Most of them unsurprisingly retreated, but we did meet one bloke who - remarkably - had made it both up and down without any metalware. He did however seem a bit shaken by the experience. It doesn't seem to cross people's minds that although it's a standard summer path it faces north and is pretty steep and bare on the upper 100m.
There wasn't anywhere near as much snow below 800m, and also less by aspect - we came down the more gentle NW ridge which was patchy (although still had plenty of good crampony snow to use). That was a couple of days ago, anyway - things will have changed a bit since then, as ever.
