Most tube mods have their venting at the bottom so it would seem that top down would be better. However, with top down and a tear in the wrap you might get a continuous firing and a much higher risk of thermal runaway.
I re- wrap my batteries at the smallest sign of a scratch and I hope that everybody using replaceable batteries do so ...Most tube mods have their venting at the bottom so it would seem that top down would be better.

Sure, but there's always the risk that you miss a tiny scratch, or get the battery scratched when inserting, and then you're in trouble.I re- wrap my batteries at the smallest sign of a scratch and I hope that everybody using replaceable batteries do so ...
The mechs that I use are lined inside (at the top as well), so this issue is close to impossible ...Sure, but there's always the risk that you miss a tiny scratch, or get the battery scratched when inserting, and then you're in trouble.

So, which way is best to put the 18650 into a tube mech mod?

Considering the power flow, it has to remain topside up. Electricity flows in the path of least resistance. To orient batteries in reverse would likely require wiring, which would become an issue for lower resistances. Might as well build a box at that point so you can make use of the proper wire to carry the amount of current you need. I do believe the end result would be... Undesirable to say the least. Seeing how upon making contact with both ends of the batter starts the current flow, you'd still be wiring the positive to the 510.
Also, if you're worried about venting, you should reconsider what you're doing. Building too low? Build higher. Battery wraps toast? Toss them and get new batteries. I don't rewrap anything. Therefore if the manufacturer wrap comes off, they get tossed and a new battery replaced it. Unsure of your battery can output the current you need? Find a battery that will work for what you need it for. Better safe than sorry. Getting "hot switch" on your mech? Clean your contacts and threads. Also look for "stray arc" marks on the battery(ies) you're using. "Stray Arc" is noticable by dark rings or "pits" on the contacts in the mod of on the batteries themselves. I don't know the term for it, but I have a good idea why it happens. Dirty contacts and or not fully pressing / depressing the buttons (especially on unregulated tube mods) causes those rings. I watched it happen once on a "test rig". When working with pure silver, gold, copper, brass, stainless, and rhodium plated pins.
But yeah, there are also mechs that vent from the top and sides (see V3Tronix Flip). It had 3 fairly good sized vent holes on the side of the mech. Also note that the batteries we use do not always fit snug into our devices, which may aid in the venting process. However, I'm no scientist, just my speculation is all.

Why would you need wiring to insert a cell in positive down? Either you are massively off the mark, or I have completely misunderstood your post (and if I have I apologise).
My question is about whether or not it would fire the atty or maybe fire the button. Burning ones finger.

Well, either way, makes me nervous. Sorry, not sorry. I would think that adjusting the orientation at all would affect the resistance or have an affect on power output.The way the battery is pointing doesn’t affect which end of the mod heats up. A circuit is a circuit.

That's the Broadside mod. It has that delrin lining specifically so that the battery can be inserted positive-down. Otherwise, you'll want to use positive-up, for the reasons stated in zoiDman's diagram, above. Yes if your wrap's in perfect shape, it shouldn't matter, but in case something goes unnoticed, proper orientation ensures current is still limited by the atomizer coil and gives you more time to correct the situation.Inspired by this video
