And for those who are laying down separate tracks for each drum piece, I'd highly suggest getting Superior Drummer 3. All the individual drum parts can be mixed within SD3, along with efx. Thus freeing up your Sonar tracks to where you only have to create one track for the drums. *just my 2 cents on that issue 
You don't need SD3 for that, most have inbuilt mixers, some have limited options as far as FX, others not so, you can do it in BFD3 (which has more FX available than SD3),SD2, AD2, Ezd2 and on and on. Personally I still prefer individual tracks for kit pieces and overheads, room, ambient etc, ability to use other 3rd part plugs you may have etc, just more options and control. (
I have SD3, but much prefer BFD3 still)
