One of the posts here says that the flavor of the juice is different with different devices. I would like to know what device people think gives the BEST flavor... would love to start a poll when I am alloud to

maybe a member who can could do it for me?
Good point and one to keep in mind for all juices. In fact, having a 510 and an 801 around isn't a bad idea to check for just that. The 510 enhances some flavors - the stronger flavors seem to come out in the heat and subdues some. The 801 really can bring out the lighter flavors. With RY4 both the Janty (smokey) version and the ruyan#4 the dekang version - I like them both but not equally - Janty wins but the wife prefers the dekang. Hers _smells_ delicious and it is really. If that was the only juice, I'd be good with that. ;-)
.... got side tracked - both do well in both the 510 and 801 and no doubt the 901 and the 401's etc. for people that like the flavor. For those that don't, no ecig would likely change that but RY4 can be a 'sleeper cell' flavor, as has been mentioned. I contend that the reason it is usually the number 1 or 2 on any polls that have been done here is that it tastes good to people that like it, in any ecig.
This is not true of my other favorites - only the 510 atty brings out the full flavor of DV's Habana Reserve and Absinthe while the Black Currant does better in the 801 janty stick while not bad in the 510.
