To add to the confusion, remember when someone write, don't use this with that, its not necesarily( oh spelling) because the two things don't go together, but just that they specifically don't like the combo..
Like the cartos: Many will say that Boge is better than Kanger, but they havent tried the new, updated Kangers. I have tried both Boge and old and new Kangers, and can say that the new Kangers kick Boges .... bigtime.. But again.. that MY opinion. Haven't tried e2's cus of all the bad rewievs.
To not go insane with all the choices I decided to make a list of what I find important in a PV.
I decided that I was strictly a carto person.. Attys are long gone for me, dripping sucks IMO, so I trolled the forums and web for anything that had cartos. Here there are things that don't go together, like the smoore cartos wont work on a manual Kanger, but is fine on an auto...Tried some 510 cartos but feel they are way behind 808, so again, I made a choice. Cartos, 808's. Then I researched batts, tried a couple. Found out there IS autos that perform, so ok. Cartos, 808's, autos. Then pcc's and so on. I've come up to speed on 808's but have to follow closely as the market changes all the time. Have to say though, I want a cigfeel experience, so that steared me towards kr8 too... I have egos and a riva, so I know what i'm "missing" out on..
If youre looking for something with with a little more kick to it, the kr8 will give you that, cus of the higher voltage, BUT since your allready on 1000 mAh batts, its prob not for you, cus the biggest kr8 batt is only 380mAh.. Low mAh bites... but htey are finding ways to get more into small batts, so thats great.
So maybe you should look in to the mod world?
