Hello and thank-you in advance to anyone who responds. Never posted on a forum before so pls bare with me 
I'm in Canada and from what I've read I understand ordering the actual ecig from across the border won't be a problem, it's the nicotine juice that should be ordered in Canada to avoid border issues?
The reason I'm asking is because I'm a heavy smoker who, after much reading, is of the opinion that a smaller battery unit may not completely satisfy my cravings. While at the same time in public I think a life like would be better. I guess my question is, Can I buy say a 510 kit and then get mods for say longer battery life and better vapor that will fit the 510 to use at home? Or should I just get a bigger one and save my $$?
Hope I didn't confuse anyone too badly
