I only have the 22mm Nudge, but I would have to say it's currently my favorite small squonk topper. I personally prefer single coilers, but in all honesty, I think I'm going to pick up the Nudge 24mm as well seeing how much I like the 22.
The large cap is too airy for me, I'm using the one with the small air slots. The smaller airflow cap on the Nudge 22 has similar airflow to the Serpent SMM if you are familiar with it.
Not sure if you are planning on dripping or squonking, but it's a great squonk RDA. Surprised more folks aren't talking about it. I like it so much, I actually have all of the colors in the 22 except for the red.
I only own two double coil RDAs, but I think a Nudge 24 will join the collection.
