Welcome to the Forums! As with most good clearomizers, you'll be able to get great flavor but the vapor production may leave a lot to be desired. MVP2 maxes out at 11 watts iirc. Although you can still get an RDA on there and get much better results, you may want to look into a new battery as well. Because of that limitation, you won't be able to fire at anything under 1.1 ohms, so the kanger .8's are out of the question.
If you want good regulation for not a lot of scratch, the iStick and any high airflow RDA (Mephisto, MutationX, Doge, Little Boy, Dark Horse) is a good way to go. 30 bucks for the mod and 15-25 for a decent clone should put you at the beginning of your next step in vaping. It may seem like a little much of an investment but you'll then be able to rebuild your coils and save a lot more money over time than with buying standard heads.
Speaking of heads, your MVP is reading your tank at 1.9 now because there's gunk buildup on the coil, or it's starting to degrade; therefore gaining electrical resistance.
It may not be the answer you were hoping for, but its a viable option indeed.

Hope this helps!
