I agree with beau 100%
Never use your spurs unless you need to. If he is knows your legs cues well, don't use spurs. if you use spurs when your horse's doesn't need it, it could cause him to become dull.
I never wear spurs on my horse, ever.
If he is showing irritation when you use them, it most likely means that he is uncomfortable with them and they are making him hurt or something. Horse's don't show irritation for the fun of it, they are always trying to tell you something. Always
I barrel race and I never use spurs, I don't even kick my horse, unless he is not responding to my cues - but even then it is like a gentle tap of your hand on someone's shoulder.
