I still totally dig the Cisco 306, but there are some new premiums out there...
Cisco sells an HH.357, which uses his coil. It's a hybrid 306/510. It makes a rediculous amount of vapor and has a pretty good flavor. I don't use them because I keep flooding it on a REO, so I'm still using his 306's. The HH.357 is AWESOME if you actually drip, and tightly control the amount of liquid. True dripping is too much of a pain for me, so I use
tanks or bottom feeders, making it difficult.
The word is that Cisco and Hanna (the builder of the HH.357) have something new coming any day that's supposed to be great... A carto based on the HH.357, perhaps? Also coming is a Cisco
tank that uses an atomizer, not a carto. Will be interesting to watch.
Also, iKenVape's i06 is pretty nice... competes well with Cisco's 306, and works as well. But, Cisco is almost always in-stock, iKen's unpredictable availability just isn't worth dealing with, IMO.
You just can't beat a Cisco 306 for nine bucks...
