Making your own juice is a good idea but unless you are really into it, it can be a PITA. Lots of trial & error, some you will like, others you will think 'what is this crap'.
Anyways I suggest that you get some pre-made just in case. If you are looking for the tobacco type flavours, try
1) 24 mg DK - Tab
2) 18 or 24 mg Export Eh
3) 18 or 24 mg DK-Camel
4) 18 or 24 mg Do More Eh
All can be purchased from Vapables.com
Last but not least get yourself some LR attys for the 510/eGo. The LRs will make you wonder why more people aren't
vaping instead of using the cancer sticks.
Have fun and welcome to the wonderful world of
vaping!
