pretty much what I do now. I havn't been on an advanced riding course (should do really) as I probably picked up some habits.
I love the caveat, only go as fast as the corner will allow, great if you know the corner in question.
Unknown blind corners with no tell tail marking I tend to take it easier. I tend to use the white lines to tell me how the road is, use other signs like railway tracks (roads tend to be 90' going under rail tunnels) and telegraph poles to plot the hidden road ahead.
