If you're getting bored of playing the same old rudiments over and over, try mixing up various combinations to create new patterns.
Here's one I've been using a lot lately, it works great as a warm up exercise too!
Here, I'm going though singles, doubles, paradiddle and a triple paradiddle to finish. Putting paradiddles at the end of these combinations allows you to flip the sticking and start again, leading with your left hand. This also allows you to see how your "left lead" compares to your "right lead" and encourages your weaker hand to catch up!
I like to practice rudiments in this way, as it puts them into more of a musical context. You're very unlikely to find yourself playing one sticking all the way through a song, so it's worth practicing moving from one rudiment to another!
