What are the best BBQ sliders?

Yesterday, I posted pics of sliders from SLAB BBQ. So, sliders are on my mind. I've had BBQ sliders at several BBQ joints. (I had 3 BBQ sliders this past Sunday, in fact, in Nashville.) Particularly if the BBQ joint lets you mix and match, sliders are a great way to sample a joint's meat offerings. If you've eaten BBQ sliders, which are your favorite(s)? Sliders often come in groups of 3, so which 3 sliders (They don't all have to be from the same restaurant.) are your favorite?
