i can definately give you run down of all the single stroke double bass techniques but the pedal your using is really quite important - although the pedal dosn't make the drummer (its possible to get any speed on any pedal with work) the pedal is a big part in playing relaxed while your playing at high tempo's.
I actually hate my current pedal, the DW9000, but i buy basicly any pedal with good reviews when i have the money, just to try it out - you know? eeeeeebay is handy, may lose some money selling it on but its worth it to find out how the pedal feels first hand (with all settings to your own).
anyway, apart from the AXIS (which is my next purchase) i have tried basicly every pedal out there and all the single stroke techniques (screw heel toe its for pussys, but can be applied for amazing grooves - i just dont think its a replacement for single strokes like most ppl do), ill give you a rundown of what my humble opinion is of each pedal//technique, right after you give me some answers to these questions
1. what is your current pedal?
2. do you want to go pro equipment or affordable equipment? - keeping in mind here complete noob equipment is never an option imo so nothings dirt cheap
3. how fast do you actually want to get? i.e your prefered genres of music
1. im using a dw 7000 atm, its got a double chain
2. im 16, and no job so i cant spend much more
3. as fast as possible, i like rock/metal drumming etc but im into everything
