Hiya mrfingers.......yeah, I'm totally hearing you about that.Lots of “sticking” advice here but short on footwork. Don’t forget to tie in your basic foot groove patterns which makes for more interdependence and syncopation possibilities with your “handiwork.” You get to figure out the diff between playing 1-3 vs. 2-4, especially when ghosting notes or ending fills etc..
Frank Briggs had a drumeo lesson a while ago which had some great ideas for building a vocabulary.
He had this simple, amazing, useable and practical PDF download which I am now using.
I use the cybal rhythms while doing a simple single parradiddle between my right and left foot.
It really opens up the left foot.....and it's a lot harder than what I thought.
I also do linear stuff incorporating the feet into certain patterns.
