you CAN rebuild on the more limited APVs (more limited imo - vapes between 1-3 ohms, around 3 amp limit, 11-15w max).
I was happy with this setup for quite a while (on a SmokTech SiD - similar specs I'm sure): 1.4 ohm single coil setups worked great for me! It's nice to have a wider range though - my Cana mod lets me go down to like .6, and my mech will go as low as I want it! (I dont like much below .7 though.. built a dual at .5 once the vape gets HOT).
you can take shorter hits at lower ohms because the coil doesnt take as long to heat up.
Its all about what works for you though!
