This was all very helpful!  Thank you for elaborating on the issue!  Now I know what to do to fix any leakage in case it happens! 

I keep shop rags around.  In my car, in my work laptop case, in my desk at work...places like that.  My leakage issues are typically limited to the things I mentioned above; warm days or drastic altitude changes.  When a tank starts to leak, I wrap a shop rag around the air holes or slots and blow into the tank to blow out the liquid that has leaked.  After that, I fire the mod to heat the coil and simultaneously blow.  That will burn off any liquid that didn't get blown out.  Then I return to my regularly scheduled vaping session.
Preventing leaks in the first place is key, as you know.  Keeping your tanks in good working order (regularly inspect O-rings and gaskets, check glass integrity, proper installation of coils, etc.), don't over-fill, keep tanks upright (even the best tanks will leak when they are on their side), and keep in mind that thinner liquids are going to be more prone to leaking will help prevent leaks from happening in the first place.
Also, one other cause of leaks is NOT vaping a tank completely.  If a tanks with liquid sits for a couple of days without being used, the vacuum that is created through the act of vaping will slowly release and liquid WILL leak out. 

Leakage is actually an issue that can arise with any tank, not just the "Beast" line.  Atmospheric conditions, drastic altitude changes, VG/PG ratio, coil priming method...all of these can lead to leaking.  I have Baby Beasts and Cloud Beasts in my daily rotation and, with the exception of the occasional extra warm day or trip to the mountains, I don't have any leaking issues with any of my tanks.  They both have their advantages and disadvantages over each other.  The Cloud Beast has a larger capacity, but the Baby Beast is slightly more convenient due to its more compact size.  They are both workhorses and I really wouldn't rate one better than the other. 

Welcome!  You are in luck.  This one of the friendliest forums I've stumbled into.  Lots of folks here with a lot of great experience.  Quick note, I'm not one of those folks.  I just started one month earlier than you.  But like every enthusiastic newbee, I still like to share what I think I know, lol.  
Regardless, great choice and again welcome!
