The ADDAC 103 T-Networks is great, does a nice 808-ish Kick then some great other Toms, blips, etc that fit in and around other elements really well.

Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
