They give a bit more attack, I have them on both of my bassdrums, I love the sound of my acoustic bassdrums, but for fast playing it doesn't matter anyway because I trigger my bassdrums.
I only use them if I play rock, if I play any other music type, I use clear heads without the falam slams, and if I play metal as I said, I trigger them.
But for what you say I recommend you get them. As Angra says, they also make you bassdrums last longer
