Hey first timer on this site was reading over this post not sure if anyone has mentioned it or not, but which one lasts longer i used to have a Delta II with Xpro M45 battery, basically used 70/30, but the supplier i used to get my vap from moved away so now im going to stored to get the eliquid. I currently am using a Arctic Tank which is .2 ohm coils which i use the Xpro m80 now cause i have to go to 60 watts compared to 35 watts i used with my Delta II but im noticing that th Arctic eats up the juice and was wondering if the 50/50 would last longer for this tank or the 80/20? Thanks
