This is the type of style I was going for with this. The drums really set the groove for the mix, and thus varying them too much (they're actually more varied in my mix than they are in the Pendulum track) I feel would alienate rather than contribute to the track as a whole.
I completely disagree with your statement about the samples holding the mix back. On the contrary, those percussion samples, I think, are some of the best I've ever come up with. And also I don't know about everybody else including you, but I can still hear the fills perfectly fine at :50 and throughout.
It's not the 'traditional' style of DnB, it's supposed to be the more aggressive, 'newer' type. The snare does have a lot of 'oomph,' and that's characteristic of the specific genre I was going for.
