Okay, so as said I could once play 270 BPM 16th notes with full leg motion, with a bit of ankle motion, while my left leg was tense. Now I can't do 150 BPM.
Now, I know that it was a really bad way to play double bass (drums). (I've played about 10 months double bass) So I tried to do ankle motion. I practiced that for a while, but can only do about 140 BPM now (with ankle motion). When I try to play above 150 BPM, my left foot can't keep up.
Should I keep going practicing ankle motion, and play that way? Or should I stick with the way I could play really fast? (I can't get near 270 bpm at all now)
