I played with a drummer once that triggered his kicks and it sounded really cool. He got a nice full sound every time, and could still play soft, as they were velocity-sensitive. I believe you can even adjust the velocity, so if you're playing death metal, I'd reccomend just triggering the kicks and you'll get a nice accurate beat each time. A disadvantage might be that it's alot more equipment that you'll need. Triggers, drum proccessor, and a full PA just to change your drum tone.
Also, if you're waiting on making the purchase, then you might settle for metal click pads with hard mallets. The sound was difficult for me to get used to, but the advantage was that when you're behind the kit, you can hear each beat precisely and play more accurately. Just remember that any big change like these that you make to your kit might take time to get used to, but you should be happy with the results.
