I think of it like counterbending- I don’t ride a test with it, but having a tool is helpful. I just don’t call it “straight”.
However, playing with bend and angle is all great-- BUT–I wouldn’t ask for something like too much angle- there is 30 degrees for a reason.
Knowing why and how to “bend the rules” is critical. Don’t start guessing. there are reasons and theory behind the movements.[/QUOTE]
My coach/trainer is well enough educated to know how to vary the movements according to what the horse in training at this moment in time needs to develop, whether it is more angle/less bend on one side, or less angle/more bend on the other with our shoulder-ins.
I think of the test patterns as something that you ride to display your training, and the rules exist so that everyone is doing a standard move.
The last thing you want to do, is take the test patterns as a training module, and only train “to the test.” If you did that, you’d never do lateral work at the walk, only start at the trot. And you certainly don’t need to master everything at one test level before moving on to components from the next. Of course, some things do ladder into each other, but some things don’t.
So yes, for the test there is a narrow, specific definition of shoulder in, and you would need to be able to do that well for the test. But as far as building lateral mobility and hind-end engagement in a given horse, it might need all kinds of variations on any move in order to get to a good performance on the narrow, specific definition required by the test.
Whether someone wants to say that only the test definition down the rail is “real shoulder in” and everything else is something else, or whether you have an expanded definition of shoulder in as a gymnastic exercise, doesn’t matter that much really. I find it easier to call everything in this family of moves “shoulder in,” and differentiate it by “on the circle” (which changes the exercise quite a bit) or “with increased angle,” etc. But absolutely, no, these moves do not turn up on any test and therefore not in the FEI rules, and from a judges perspective therefore aren’t “real shoulder in.”
