I will chime in and recommend Avid Vaper as well. I just got their 2 atty + drip tip combo for 20 bucks. I am blown away!
I was using standard 510s for the first 2 months of my
vaping. One month in I got a Joye 510 LR and hated it. Two months in I gave the LR another shot and I was liking it more. After a full day of breaking it in I was hooked on the LR. A few days after I went back to my standard 510 and it seemed so lame! Well, as they say, the LRs dont last as long and 3 weeks into my new found enjoyment of the 510 LR it popped!
I had to get another LR asap as I was very unsatisfied with my regular 510s at that point. I wanted to get an LR 306 from Iken as I see so many people recommend him, but he has been out of stock for a while. So I went with the next most talked about Cisco. Avid vaper is Cisco's own web storefront (or so I have been told) and his 2 +drip tip deal was great for a newbie like me who never used a 306 before. My order was processed the same day and was in my mailbox a few days later.
I tore open the package like a rabid animal. As a bonus Cisco's atties are sent out primer free so I didnt have to mess with blowing out nasty primer or anything. I put it on, snugged on the drip tip, dropped in 5 drops and waited an agonizing 30 seconds to let it soak in. Took a toot and BINGO!! Jackpot! I was blown away from the very first hit! Tons of vapor, nice TH and all the flavor was still there. I have been cranking on my first one for about a week now and I couldn't be happier.
Sorry for the long winded response, but I just thought I would share my first experience with a 306. After re-reading the OP post I noticed you were looking for standard 306's and I cannot say how they perform. I have always read that the 306 is THE drippers atty. I would hazard a guess that a standard 306 will perform quite well also. Like anything in the
vaping world, you have to give it a shot and see for yourself if its something you'll like. If you absolutely hate it there's always the classifieds here on ECF. Or just hang on to it and try it again down the road. Sometimes our first impressions can be misleading. Vape on!
