Most trainers I know.. the best trainers I have seen ride.. probably would not "win" and equitation class. I would not and did not and I tried... but I got the horse trained.
Pretty is not necessarily good riding.. you need more than that and good riding is not always pretty.
I had lots of lessons.. and in the beginning that was good. Basics are pretty universal. At some point it got to be interfering and when that happened, I started really riding..
