I've been researching egos & accessories for the past six weeks and purchased three ego c kits and two ego twist (piecemeal kits). I purchased first ego c before I knew about the twist and third and fourth for two people who won't experiment with anything. I couldn't even talk them into ego at all at first they wanted cheapest thing that looked like a cig until they realized batt life is important and I'm not messing around with juice/cartomizers/cartridges all the time like they were. I couldn't justify spending any extra $ on their kits plus I want them to be happy to be making the switch. So no twist for them. Now I've got only the twist and I have tried about 25 different juices on the ego type a atty/tank set up on twist and can only get a good flavor at the lowest voltage on all of the flavors. Most of them taste burnt w/ volt set qtr to halfway the marks are just too small for me to read. None taste better at higher voltages. This is not the case with my clearo/drip rig set ups so I don't think it's just something I'm doing, but when I checked out the Safe Vaping Power chart is appears that a type A atty (I believe is 2.2 ohms) would be safe vaping at 3.25 to 4 volts. So I would think that out of 25 different juices everything from fruit/Light & heavy tobacco/liquers/caramel apple from at least four different vendors in three different pg/vg ratios that i would be able to get some better flavors out of at least one or two at higher voltages. Am I wrong or is it really not necessary to go with a twist if you are not going to be using anything other than ego c atty/tank? I ask because I know I'm going to be getting more kits for others in the near future (just call me your local PV pusher) and if I am wrong then I'll push harder for them to invest a few extra $ now to pay off in the future by way of variety & compatibility. Plus if I'm right then I'll just get myself a regular ego c batt to use with that one set up which I will probably always use for riding on my bike at least. I used to be one of those bikers you see riding down I95 with a cig hanging out my mouth at 95mph. Now I can really mess with people.
