wana get a mechanical mod, need suggestions

Id say go with clones to start, until you find the mod you love, then buy the authentic if it's in your budget. Just my opinion.

I was just looking into it and yea. Positive facing the atty is best. That way if the wrapper were to fail the mod will just fire instead of shorting.

The typical cylindrical battery is a can shape which is negative, and the positive is in the center at the top.

The cylinder part of the can is usually wrapped in a plastic wrapper - lots of older batteries were painted, not wrapped, back in the days before there was so much plastic;

That plastic wrapper is really the manufacturer label; it isn't designed as an insulator material; the material just happens to be plastic usually.

A bottom firing tube would be depending on that outer label to act as an insulator;
