any suggestions on battery life for the 18490 vs mini. both with a RM2 atty. Do they vape the same as far as throat hit etc. how about battery life between the two. I currently have a metal 2.1 with a RM2. That one allows me to go the whole day with juice and sometimes I will have to switch to a second battery to finish my day. Does anyone think with the mini I would be able to last the day with 2 batteries or 3. I know it is all subjective but anyone that has gone from an 18490 to a mini with info would be great. Also does the wood hit the same as a metal 2.1? Thanks in advance for any suggestions...
