Hahahaha alright hmmmm.......the only thing that pops from my head(and has me addicted) which actually comes from the unreel drum book which features vinnie c. is a 32nd double storke exercise which goes something like this...
1 e & a 2 e & a 3 e & a 4 e & a
RR L R L RR L R L RR L R L RR L R L
Its pretty simple and advised that you move the double stokes down to the e & a like this...
R LL R L R L RR L and R L R LL
Well for me its pretty fun to practice and I always get a kick outta it. I may try to post a vid of this if i can get my hands on a camera...
