if you're going with VV and tank mods, it might be best to keep your nic level where it is or even cut it in half to 6mg - reason being, you will go thru much more liquid with high-powered rigs than with a mini. You're gonna want to smoke that VV like a freight train - unlimited almost liquid, big battery, who could ask for more, right? Except, more juice used, means more nicotine intake.
Now let's review some math: Let's take your 36mg/ml bottle for instance. in 5ml you would have 180mg nicotine (5ml x 36mg/ml =180mg in 5ml). If you cut that 5ml with VG or PG by 50% (add 5ml of PG/VG) then you will have 1 0mils of 18mg/ml liquid. Your 11mg liquid cut 50% gives you 10mls of 5.5mg/ml. Pretty simple, right?. Now, let's say, you have another bottle of 11mg that's 5ml and you want to punch it up. If you combine 5ml of the newly created 18mg with the entire 5ml second bottle (11mg), you will end up with, yes, 10mls at 14.5mg nicotine per mil (18x5=90 plus 11x5=55 for a total of 145mg divided by 10ml equals 14.5mg/ml). Alternately, if you have 5ml of 36mg/ml and add 5ml straight to the second 5ml bottle you will have 10 mils of a 23.5mg/ml solution (36x5ml=180mg plus 11x5ml=55mg divided by 10).
oookayyy, TTRP, I hear you say, that's fine and dandy, but I'm a newbieeee, I don't have any way to measure things as small as 5 mils! Is it a teaspoon ful? No worries, go to the grocery store and buy a few of the twist-cap travel bottles over where the travel-size stuff is (and some laytex or non-laytex gloves (you don't want bacteria from your hands growing in your juice do you????) and a permanent type marker). Wash, rinse, dry the bottle(s) and clear yourself a sterile area (dining room table for instance) to play mad scientist. Don your gloves. Grab a full 5ml bottle of your 11mg liquid. Use the marker to draw a line on the outside of the bottle to indicate where the top of the liquid in the bottle is (the 5ml mark). Pop the dripper top and dump the contents of that bottle into your newly washed, rinsed and dried travel bottle. Cap this, and set aside. Use the now empty 5ml bottle to slowly and carefully measure out 5mls of the 36mg (or 18mg or 0mg) solution to the mark you made with your marker. Add this to the existing solution in your travel bottle. Cap. Shake *gently* and then pour out half (5ml) back into your original marked 5ml bottle. Pop the dripper top back on and cap both bottles. Clearly mark your travel bottle that now contains the remaining 5ml of liquid with the strength and date 'born' and store all your liquids in a cool, dry place away from children, pets and inlaws. Wipe down your mad scientist work surface of any spills, toss the gloves, wash your hands, load up your rig and celebrate having aced both Vaper Math 101A and ELiquid DIY 101A in one day.

Good luck and Happy Vaping!
