I perfer the Suffocation style to the alternating style. Sounds sooo much heavier (to me anyway). The alternate kind has a wierd grooviness to it, which might be useful for certain stuff but it's not my favorite.
When your programming the blasts, try some untraditional stuff. Like I did a bass/china cymbal/low tom one that sounded pretty cool. Also, just for kicks I did a bass/ride/cowbell blast!!
