NaRDA RDA are not tall at all and come with a very small hole for airflow. In fact a lot who use DL need to bore the hole out more.
NaRDA is only 31.8 mm tall. Based off what
Fast Tech says. The newer cloned versions seem to have made the hole a little bigger, more like a cyclops style. You can probably crank it right down to near nothing.
If you're going to drip regular style then maybe the added 7mL juice well on the Dot Mod single RDA would suit. On the other hand if you're going to get into squonking even a humble 2 mL juice well would suffice. Wick can hold roughly 1 mL of juice in general.
The Dot Mod single coil RDA uses a similar cyclops style airflow. You get two 5 mm long holes you can dial in where you need. It is 22 mm diameter. Not seen a spec for the height yet. Obviously I don't got my grubby paws on it. *chuckles* My normal price range I pay for RDA falls to half the cost of this particular RDA, or lower. Yep, I do okay with $30 or less RDAs.
If you're looking for something like the Nano
Wasp, get the Nano Wasp. It has the cyclops style air flow yes. That aside you can dial it in rather tight if you like. Believe I'm coming in at .5 mm on each side. I'm not sure that's 100% accurate but eye balling it, it's a very thin hole.
Besides you can get the authentic for just around $12 off of Fast Tech. I don't think you'd go too far wrong to get it and try. If not what you want you can always PIF, or trade out here on the forum. Got 3 Wasps myself and enjoy them. Not looking for more but wouldn't turn one away either.*chuckles* They're good RDAs.
Ah, here's the sinker. Wasps are only 27 mm tall & 22 mm diameter.
Let me add this disclaimer. All the above is my opinion and based on my four to five years of vaping. I'm not telling you what to do. Sorry, I just don't do that. You can do what you choose. I'll be happy no matter what. *chuckles* You're asking for advice/opinion, I'm just offering what little I have.
