every carto manufacturer, and every variety of atomizer will have different effects on the juice...the bridge mesh consistancy, voltage, ohms, atty/carto materials, device...all have an effect on taste...so you need to experiment and see what you like because everyone is different...there are some similar trends though...cartos most everyone likes...they are consistent..for the most part..and offer convenience and good flavor..try a different supplier or manufacturer cartomizer...as for atys...ive tried almost all of them and ive found that rn4081's and 801's are the best mix of tastiness, vapor production, and quality(read- dont die in a day)...some 4081's are different though so be careful! I have a 4081 from when i first bought my copper 6 months ago that still rpoduces vapor and taste like the day i received it!!!!!!!! honestly...it is still my favorite atomizer! its quite amazing...im vaping on it as we speak...ive gotten ones from other places that started tasting like crap after 10 puffs....so all things are not created equal...including cartomizers...i dont like the 510 cartos...tried them and i thought they sucked...but then again...i dont really like 510 attys either...i think they are alright...but theres much bettr attys out there...801's vary...even from the same ive had 1 that wouks awesome and 3 that die after a day! i know...very weird...and i take care of my stuff...clean them safely and dont use very high voltage...anything over 4.7 volts is too much for me and i think it kills the flavor and its just way to harsh...but everyones different...i would really recommend trying the 4081 atomizer...it is a work horse and provides great flavor for me...i mean GREAT!!!! but youll have to get an adaptor or new device for that...ive heard a couple people say thei dont like v4l cartos...and a lot of people say they love them and wont get their cartos anywhere else! ive been wanting to try the cartomizers from royalsmokers.com(china wholesale comapny) they prodice a CE2 cartomizer that utilizes ceramic materials instead of polyester...ive heard good things about them...last longer, taste beter, hold mroe liquid, dont leak as easy, and they have a choice on the XL to pick what Ohms ytou would like the carto to run at..which is resistance..the lower the resistance the less voltage you need so a 1.5 ohm cartomizer will get hotter and prodice more vapor than a 2.5 ohm carotmizer at the same 3.7 voltage...BUT the lower ohm carot will provide more watts(power) and might cause the liquid to taste burnt or bad tasting...so i would go with a middle of the road ohm carot for the first time...then go from there...good luck and i hope this helped a little!
