We did one of these "puh-duh-duh" exercises awhile back. I like this sticking. It rolls off the hands nicely and makes for a relaxed warm-up.
This time though, we're going to add some paradiddles into the fold, making it more difficult on a few levels. Not only do we have to deal with the gear change between triplets and 16th notes in general, but often we're moving swiftly between double strokes at the triplet rate and 16th note rate.
