Of spurs and self carriage

My spurs are now part of my uniform while riding Delphi. In our lesson this week we are still working on flexion and counter-flexion at canter. When I make a deliberate GIVE (breathe, two, three, four) after a flexion, it allows Delphi to do one of two things: 1) completely fall apart onto the forehand (which means she wasn't in a good place to begin with) or 2) travel through in self carriage. Either way I must ALLOW Delphi to find her own self carriage or reveal inadequacies that can then be addressed in the next cycle of flexion-and-soften. With spurs on I do find it easier to nudge up the occasional little extra energy and when I want the spurs, they're there.
I'm currently using these stainless steel rollerball spurs with Delphi.
