It is a good idea to record trigger "splats" for all drums. Their primary reason is to capture the hits without any bleed. I always record them even if I'm not going to use sample replacement. Why is that? You can use them for many different things. The raw sound you get from the triggers is just high end splat. It can be blended with the kick or snare sound. It can also be compressed and limited hard, because the bleed is nonexistent. You can also use them to drive gates using sidechaining functions. The result will be very accurate. Remember to mute these tracks when monitoring the takes!

DDrum makes the most commonly used drum triggers. They are very good and reliable. Just don't buy the cheap Red Shot triggers. They work but the design is very poor!
