The problem you will run into when using subΩ clearomizers (with stock coils) is that you cannot "fine tune" your vape. On a mechanical mod your voltage drops as you vape, with a regulated mod this does not happen. Your first hit is just as good as your last hit. And then there may be a problem with under/over powering the stock coils given you have no way to "fine tune" using a mech mod.
Here's an example using the Atlantis new v2 coils. Below are the recommended ranges (per Aspire) for these coils. I have not used these coils so I can't say how accurate these ranges are.
1. 20-30W (0.5Ω coil)
2. 40-50W (1Ω coil)
3. 70-80W (0.3Ω coil)
1. 0.5Ω coil - On a mech mod with a fully charged battery (4.2v) you will be vaping at 35.28 watts. As the battery drains your wattage will go down. At 3.6v (when I normally recharged the battery) you would be vaping at 25.92 watts. You may have to take a few pulls without firing the battery to keep from getting dry hits when the battery is fully charged.
2. 1.0Ω coil - On a mech mod with a fully charged battery (4.2v) you will be vaping at 17.64 watts. As the battery drains your wattage will go down. At 3.6v you would be vaping at 12.96 watts. Pretty dismal performance (underpowered) running this coil on a mech mod given the recommended range of 40-50 watts.
2. 0.3Ω coil - On a mech mod with a fully charged battery (4.2v) you will be vaping at 58.8 watts. As the battery drains your wattage will go down. At 3.6v you would be vaping at 43.2 watts. Again, sub-par performance (underpowered) running this coil on a mech mod given the optimal range of 70-80 watts.
In conclusion, I wouldn't run these coils on a mech mod. I would get much better performance running these on a high vv/vw regulated mod.
So the question I have for you guys is: Is it really as simple as slapping a sub-ohm tank on a mech mod and then monitoring the voltage levels of the battery or is there a lot more involved?
Knowledge of battery safety, Ohm's Law and Amps are all important when using a mech mod even with clearomizers using stock coils. The CDR (continuous discharge rating) of your battery needs to be high enough (with headroom) to support the ohms of your stock coil .
I highly recommend you spend some time with

Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.
OHM'S LAW
Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to
vaping.

* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
