@jr1xt1 i have the D020 bubbler and it works awesome with my Solo and my Arizer Air. With the Enano I didn't think I had enough volume. I ended up getting something else to work with my Enano. I bought the D022 bubbler. I think it pairs better with the nano. Other Nano users have their fav. Maybe a few would chime in.

I tried to make this smaller but I couldn't. I'm looking at this one too for my Enano.
I do use my nano on a D020, but usually only for travel. The D020-D seems like a better fit to me, too. But, I usually reach for a little more volume than that with the nano. FC-187 has a near perfect volume for me, but that part is very personal. Some like less volume, some like more. One of my friends always asks that I pull out the huge Leviathan (M&M) lattice bubb every time he's over, but he usually smokes one hits unless with me. I can clear a full can from it, but it is a workout for me.
When I use the D020 or -D, I inhale some vapor before clearing. With the FC-187 and similar volumes (FC-UFO), I usually clear as soon as vapor starts hitting my tongue.
Price can be a consideration too, but IMO you should get what you think would feel best to you - at least as far as volume goes. IME a center top dewar joint works best with nano for performance and stability. And, for flavor and effects sake stick with something simple when it comes to the perc. The simple showerhead/tire/pseudo reti percs discussed here are all good. Some recylclers (like
this) aren't bad for flavor (especially if you're looking for something that can handle dabs well, too) - but, aren't quite as simple to use, usually require a glass adapter and won't support a nano sitting on it without tipping over.
IMO, stay away from lattice/honeycombs, eggs, and other crazy/elaborate perc set ups as they will steal the most flavor, and are more of a pain in the ass to get and keep clean. Straight tubes are OK if you already have one and want to use it, but I don't really like the way they usually chug or deliver vapor.
Personally, I'm not a fan of the Pinnacle water tool and similar simple hydratubes. These little ones don't give enough water filtration to suit me, and I find for that little bit I'd just as soon go dry. I haven't tried a larger hydratube (all the rage now with cheap Chinese glass connoisseurs). They could be nice, but I'd still be worried about having the water above the nano. All should be good with it, and only real problem would be if you blew back into it, but still makes me a little too nervous to enjoy as I do with my bubbs.
If you really like dry, you should check out J-hooks. They can be nice, especially when just kicking back. I turn my heat down half a notch pop it on a J-hook and sit back to veg in front of the tube like Gandalf with his pipe. Usually get many hits with a couple stirs, and who doesn't like puffing vapor from a pipe-like setup?
The FC-UFO is also nice for sitting back and vegging. Put the nano on top and use a hose from the mouthpiece connection. Sometimes I'll use a carbed GonG adapter with this. Very simple, and almost too easy to get ripped without paying attention. I leave the nano on there for up to 1/2 hour at a time. Just cover the carb, hit the end of the hose, and release the carb to clear.
One other thing... I still think sidecars work a little better for most if you're not going with the FC-UFO. The offset of the sidecar keeps the nano from being right in your face while hitting, and allows you to monitor the can easier so you can draw the kind of hits you're looking for and will also keep the learning curve down.
