you have to remember though, 100 in velocity sensitive programs like SD2.0 won't have the max volum hit, the sample at 100 will be the sound of the drummer hitting a little bit softer than full volume, meaning, you will hear different samples. I noticed this with Addictive, i set all my velocities to 127 becuase they sound different becuase they are actaully different samples, of a drummer hitting as hard that would be normal in a performance, which in metal, drummers will always hit that hard most of the time.
To prevent you from getting your typical machine gun sound, you will need a multi sampled kit loaded or be using a multi sampled VST. Compresison helpes with this as well. A tad bit of overall drum compression on the master bus will give you enough pumping to make something like the high hats sound more realistic and emulate the volume drop after the first inital kick folowed by more double bass, as a drummer will hit a littl ebit softer after every consecutive hit.
