I am looking to move from my ego twist to a vamo. Not knowing much, I have looked on fasttech,who seem to have great deals, but the items I might need seem confusing. Could some one tell me what the ideal batteries and charger to order would be? I am looking at the deal with the two vivi nova tanks, since this seems to be a great deal in spite of the fact that I already have three tanks! Any info on the extras to order would be appreciated. By the way, I am a 67 yr old female vapor, who has been following this board for sometime. It has helped me greatly in quitting tobacco (free for over 1 yr now)!!
