Intermediate - Double Bass 5 Stroke Exercise

I found this exercise works really well for developing your 
double bass roll speed and timing. 

HH- hi hat
R - ride cymbal
S - snare drum
B1- right bass drum
B2- left bass drum


 (-) = 32nd 

R |x-x-x-x- x-x-x-x- x-x-x-x- x-x-x-x-|
S |-------- o------- -------- o-------|
B1|o---o-o- ----o-o- o---o-o- ----o-o-|
B2|-----o-o -----o-o -----o-o -----o-o|

When you get this going faster you should switch to 8th notes
with you right hand, and then try quater notes to exercise your 
time keeping. This exercise can also be applied to a variety
of grooves, fills, and solos. 

For Example:

 (-) = 32nd

C |X------- -------- -------- ----X---|
HH|----x--- x---x--- x---x--- x-------|
S |-------- o-----o- -------- o-------|
B1|o---o-o- --o----- o-o-o--- ----o-o-|
B2|-----o-o -------- -o-o---- -----o-o|
