How Do Mix Drums (using Drum Bus Compression)

Yea you know its weird.....I asked Zeus if he uses this and he says sometimes.....so I guess it just works for the slower shit or something I dunno. I tend to use it on everything I do because when I bypass it it sounds better with the compressed version mixed in.........Anyone else also EQ the compressed drums that are being blended? I usually throw a little 100hz and 12k.
 
If and when some of you guys that do use a buss comp, what do you typically send to it, the hole kit, or just some of the pieces? Do you adjust send , wet/dry, overall levels, a little of everything, etc?

Sorry if this is a dump question but Im a noob...been doing this stuff less than a year.

Oh an what Comp are some of you using for this, different from the individual track for some other flavor maybe?
