Use the nudge 22(s) daily.
Recurve is good.
C4 is good but the drip tip drives me crazy. No oring in the barrel so regular 810 won't work, has to have orings on the tip.
Waiting on the drop solo to release.....
These are my current three daily drivers for a while now. There's several I need to spend more time with, but I keep picking up these three instead, lol.
Overall, I agree with you, probably like the Nudge with the larger airflow slot cap the best (overall). They get used daily. I have every color of the Nudge 22. They seem to be going out of stock at some sites and not being restocked. I bought backups now to avoid having to try to find replacements later.
Recurve is probably my second favorite. No real complaints with mine, except the stock drip tip fits a little loose. I usually just run the tips that come with them. Don't need another addiction of starting to buy drip tips, lol. Very solid RDA, but it's also a bit heavy if using it on a light mod like the Pulse 80.
I think I like the vape on the C4 better than the Recurve. The drip tip doesn't really bother me with the o-rings on the tip. I like the stab wood tip, and mine fits very well. The main thing about the C4 that 'bothers' me, is that it doesn't seem to seal the 510 as well as my other RDAs. After a few days to a week, I've got a mess under the RDA with the C4. No big deal really, but I'm a clean freak, lol. The 510 threading/squonk pin on the C4 doesn't seem to seal as well as other RDAs. I prefer the vape of the C4 over the Recurve though. Slightly more restrictive, and possibly even smoother than the Recurve.
I've been trying to put some more time in with the Castle, and the GR1. I've had both for quite a while, haven't even built the GR1 yet. Going to have to give it a try. The Castle is a great vape and I think it will be up there for me as well, I just need to give it a chance.
The Pulse 22, Wasp Nano, DR SQ and others have been shelved since getting the Nudge, Recurve and C4.
