Lazybike, you are absolutely right and it's something I completely forgot to mention. The ring claims many lives a year, some by accidents outside of your control (e.g. oil on track from a car in front) others due to people just getting carried away and exceeding their limits. Anybody going should look at the death rates and remind themselves that a hefty bill is not the worst outcome.
I like to drive the laps at a fair pace e.g. sub 9 minutes but don't push anywhere near as hard as I would on a short circuit in the UK, maybe only 80% pace. That spare 20% can then hopefully be used if either I make a mistake or someone else around me does. Most accidents I've seen have been from people trying to drive at 100%.
Bazzer, the closed track days would be a good option for yourself as you've got plenty of track experience. The pace is generally much higher but the driving standards are higher too.
For me it's different from a day at Anglesey. At the ring I'm not looking to push 100% and just try to find a nice flow. The elevation changes are something that you just don't get at Anglesey and it really adds to the experience. The corner speeds are also higher than most UK tracks and the lack of run off and barriers gives you a much hightened sensation of speed even compared to somewhere fast like Silverstone.
One of the more serious crashes I've seen at the ring, the driver survived:
