Hey everyone. I'm new to vaping and I have been a smoker for ~7 years now. I'm excited to get into this and i just want general advice from experts. I was introduced to vaping about a month or so ago when i went over to an old buddies house and he had a new room mate who had a couple of e-cigs. They were eGo TWISTS with Kanger Evod clearomizers. He had about 20 bottles of flavors to go with it. I didn't have my pack of cigarettes with me and I didn't have an urge for one the whole night because everyone was sharing these e-cigs. I started thinking to myself...hmmm maybe i should give this a try?? So i asked him for some info and I have gone ahead and purchased my order: A 1000mAh eGo TWIST (from what I have read, this is a pretty solid choice) and a Kanger Evod clearomizer, along with a couple of e-juice flavors that i purchased from mt. baker vapors website. All of this stuff will be arriving in the mail within the next day or two and I'm very excited. But i have a bunch of general questions and I want to take a break from doing some research. So if anyone can answer any of these questions, I would really appreciate it 
Should i buy several clearomizers so i can rotate different flavors? Or should i just buy a bunch of replaceable coils and wash out my tank each time i switch flavors?
What is the best method for steeping and is it necessary for every e-juice i purchase?
How much money does this habit cost annually compared to smoking cigarettes (i'm smoking around 1 pack a week now, used to smoke a pack a day in college)?
How much upkeep is there with this habit? Am i going to have to constantly be purchasing components in order to continue doing this?
How long will a little 15ml bottle of e-juice last me? I wont be puffing on this thing all day, but i'll definitely be hitting it up every couple hours or so, and even more so when i'm drinking.
*super noob question* What is the sweet spot that i'm striving for, and how do i know if i'm achieving it? Should there be a lot of vapor? should it taste really good? What should i be expecting?
If anyone can give me just any simple advice or bring up anything that i haven't mentioned, that'd be awesome. I'm pretty confident that i've made a solid choice in this investment and i'm excited to get started soon!
Hope to hear from you guys!!
Cheers,
