I've had good luck so far with Phoenix BC 2.6-2.8 so I figured I would try the 2.4-2.6. What's the difference between the two? The 2.4-2.6 aren't working quite as well for me. It doesn't taste quite as good to me but I'm not sure if it's my mind playing tricks on me or not. I'm using a 650 ego c battery. Thanks in advance for any help you guys can offer.
