Was good to meet you Jerry, stunning bike mate! Glad it got sorted and you got out again.
I was there doing Level 3, not 4. Level 3 was great, think I enjoyed it more than 1&2, it was all about methods for correcting corners when you run wide (why didnt I do this course BEFORE I ran wide at Mallory at 100mph!) and also the angle that you attack a bend.
I felt I learnt a lot and I had a top instructor, Butch, who was a former DD racer Chris Butcher. Strange but true! He understood all the issues of racing around on a little monster and was a great help plus he was up for a more "active pace".
It was also the first day out after Protwins had added some flashy rearsets and built me a 'firm' and taller racing seat from a standard monster bench.
All in all a top day and as said there was a European Superstock chap there (I think a couple but one who stood out) lapping at such a ridiculous pace, seriously entertaining stuff!
