This could be the beginning of your journey to the dark side
I still recall the day a few years back that I finally got sick of the Roland sounds. At first it was the snares, then it was the crashes and finally it was the toms. There are still some percussion sounds of Roland that I like (and use samples of), but once I went through the initial pain of switching to BFD I never looked back.
Seeing as how you're still using the Z3 though, I presume investing more money in your rig is not an option and you'll want to make do with your TD-9 for a while longer. One trick I used to do with my TD-20 was to assign different articulations to each hand. I have a closed and an open HH trigger on each side of my Zendrum. My right hand would use the tight closed bow sound (42 on the TD-9) and the open edge (26) while my left would use the closed edge (22) and open bow (46). This gave me more variation and expressive abilities.
I still do essentially the same thing in BFD, however I use the velocity layer capabilities of the Z4 and ZenEdit to change articulations based on how hard or soft I'm striking.
Anyway, I hope that might give you some ideas for squeezing extra dynamics and expressiveness from your rig.
