Just in case any one needs to see it written out, here is my preferred primary exercise for developing doubles, which I referenced in the YouTube open roll round up. Each note should be played as a full stroke— starting and ending with the stick raised:
Read this old post for some pointers/context. It’s fairly impossible to screw up, provided you actually do the exercise, stay as relaxed as possible, and don’t do anything too crazy-weird.
I am happy to help you with any of the materials on the site, and with anything else drumming related— contact me for private lessons, online world wide, or in person in Portland, Oregon. All levels of players, and all people, are welcome.

Hi again Todd, I've just commented in the 'youtube open roll round up' post. This is another great post – this site is a real goldmine, so thank you for providing an excellent resource.
Regarding this exercise, should those full strokes be wrist turns, or as in the Chapin video, inverted movements ? Or can they be either ?
