In case you are doing Algeria, Portimao, Cartagena and some others this year. He has released a few track guides to his channel. Worth a look and subscribing (drink coffee before use: voice may make some users drowsy )
I had a day's tuition with Simon Crafer at Cartagena last month. Well worth the money and pointed out a few things that I wouldn't have normally picked up. It's not a cheap day, but I felt like I certainly got my money's worth, and he's a good guy too. Trying to keep up with him around that track was interesting too, as he's properly fast as you might imagine, and I'd be hanging it around a corner, and could see him in front of me at the same pace looking at me in his mirrors and giving me hand signals to go faster His videos are worth a watch, but if you want a more detailed breakdown on the track, Mike "Spike" Edwards does a series of "how I ride" videos for most European and nearly all the UK tracks, which you have to pay for at around £20 a download, but they 25mins long and go through the track corner by corner and step by step.
