Well done. Have you considered joining your local IAM group? Beard and sandals not compulsory :-)
They're usually pretty good for ride outs and it is a hoot "making progress" with your observer.
If you're flush with cash try Rapid Training – top blokes even if they're (ex) coppers and they're very good riders, very smooth and very fast. You won't believe how they manage to stay with you and make it look easy.
Well done again.
