I ride with two instructors and I lesson with each once a week.
I love my original instructor, but truthfully, her place is quite a haul for me, so if I miss lessoning with her due to weather/illness, etc., then I don't get to ride that week. Well, an R rated dressage judge moved close by and started offering lessons, and while I didn't want to get another trainer, I needed the saddle time.
So, I talked about it with Trainer No. 1, and she was fine with it. And she makes me send her a little report of what I did with Trainer No. 2, so she knows what I'm working on and how I'm progressing. Trainer No. 2 has no problem at all, and may even have a horse for me to lease in the next month or two.
Right now, the three of us are working on basic dressage -- doing Intro level tests and bending and learning my letters. Eventually, when summer approaches, I'll see if they'll put me back in a good hunter equitation form before the summer shows.
But I think they key is making sure all lines of communication are open, asking questions and trusting both instructors. Lord only knows, if they were teaching me completely opposite things, I wouldn't be able to do it.
I think it depends on your experience and your ability to question and think for yourself. If you are still at the stage of relying on an instructor to tell you absolutely everything, and tell you when something is right, wrong etc. Then sticking with one instructor is going to be beneficial.
Completely agreed. I'm old enough, and experienced enough to know what each instructor is telling me and how it compares to the other instructor and the discipline in question. So far, they're both teaching me the same things, even if Trainer 2 has fits about my toes sticking out and focuses on the ticky things, while Trainer 1 is trying to work on my sitting trot and some of the broader things.
Now, if this were a decade ago, I'd probably be a mess trying to figure out both trainers at the same time.
