If my experience of a day with Tony was anything to go by he really is an excellent instructor
I don't think he splits the groups into basic... advanced etc. On the day I did there was a real mix of ability, from me ( at the bottom
) through to very competent advanced riders.
We all rode pretty much the same things, with some options on the size of jumps/drop offs, and he would give feed back to each person based on their ability. So I got lots of 'outside leg down & look up'
. More advanced people got different feed back and seemed just as happy as I was
I don't want to sound like some sort of advert but he really does have an uncanny ability not only to look at your riding and know what is wrong but he can go on an communicate it to you in a way that you can understand... very impressive.
