Right now I'm using an IGO-L...they run about $15-17 in the USA for the "original" -- less if you get a clone from some place like Fast Tech..
The IGO-W is basically the same as the -L, but it has 3 posts for connecting coil(s) - 2 "negative" terminals..
I'm running 2.0 ohm coils on my -L --- you CAN wind and use sub-ohm coils.... but NOT with the MVP v2!!
Both the IGO-L and -W provide a good amount of work space for installing the coil/wick assembly...and the -W also allows the coil wire(s) to pass through the posts, rather than wound around them...
Both are well-built...some like to drill out the air hole a bit for a more airy draw...but it's a personal thing that YOU may find unnecessary....
IMHO.....dripping is the ONLY way to let the REAL flavor(s) of Boba's Bounty shine!!

Happy (vaping) Trails!
