I use 306 debridged atties from Avid Vaper (Cisco).
I recently bought an Aero 306 from them and people said it was better than other atties because it has more turns in the coil... and thus more area for the juice to vaporize on but... I think I counted 12 turns on the Aero while the new bridgeless regular ciscos... have 14-15 turns. I believe the Aero has the HH.357 air flow so... jury still out on that one for me.
I got some Io6es from IkenVape... but have never tried them. Looked at one the other day and.. it only had 4 turns in the coil. I would think, atties with less turns in the coil... will probably start burning the juice faster than those with more turns.
As far as RBAs are concerned... LOL. I have some juice (coffee flavors)... that clog up atties... after only 3 ML or so, and lots of other juice that clogs after 6 ML (and others that hardly clog at all). Can't imagine having to build a new coil everytime this happens. With me, I just throw an atomizer that gets clogged 'in the wash'... a small container with vodka or 91% rubbing alcohol in it.. and replace it on the drip tip with a new or cleaned atty. Then, when I get maybe 4 or so of these in there after having sat for a day or so... I rinse them with water and let them dry... and then I dry-burn (this gets rid of the scab on the coils). Didn't know how to dry-burn until I watched some youtube videos. This is the main thing in the cleaning... but after the dry-burn I clean them in an ultra-sound cleaner with cleaning vinigar and lastly distilled water.
Anyways... with this your atties just might last almost forever. I *have* killed a couple with dry burning... this when I was first starting and were ones that were heavily scabbed (old Joye 306 SRs which I was practicing on)... but even learned how to dry-burn the heavily scabbed atties.
With this you can use high-quality atomizers and only have to replace them very rarely, as opposed to having to try to build your own with RBAs.
Yeah, if you can get to the point where you can clean the scabs off the atomizer coils... you just made RBAs... obsolete.
But, to each their own I guess.
(Yeah, I guess there is a big advantage cleaning in using 306es instead of 510 atties... in that with the 306es... particularly the bridgeless ones... the coil is right there and you can see what you got real good, I use 10x magnification, and scrape off excess when dry burning, etc. Can't really do this with 510s.)
