if one has been used to 28g wire and low resistances on a mechanical mod then you might be a little disapointed using the 28g on the provari, for you cannot achieve the higher wattage needed to really make the 28g shine. with this being said, the v-2 provari and 28g does work pretty good, and has the best flavor of any other wire gauge. it may be a little slower then the 30g because of its thickness and wraps required, but one shouldnt be discouraged from trying this combination. a really nice vape on the provari with the 28g is 1.1 to 1.4 ohms. on a 1/8 wick a 4/5 wrap equals about 1.1Ω, but this depends on the diameter of your wick. now if you have a really small wick and need to do a 6/7 wrap, this just might be to slow compared to the 30g. the 28g at 1.3ish ohms kind of gives you the most wattage possible on the provari. another set-up i do with the 28g is a 3/4 wrap this comes in on my wicks between 0.8 to .09Ω, although it doesnt produce quite as much wattage as the 1.3 ohm coil, it is however a little quicker. with the 0.8 to 0.9 coils your set-up has to be perfect for the provari to fire it with no error messages, with that being said i used this coil set-up for a long time with no problems before going mechanical. so there is 2 pretty good vapes possible for the provari and 28g, 3/4 wrap@0.8 to0.9Ω and a 4/5 wrap@1.1 to1.3Ω. i do prefer a mechanical mod for 28g and low resistances for sure, but before owning a mechanical mod i preferd the 28g with the provari over the 30g mainly because of the flavor, and i didnt quite mind the slightly slower response time it had compared to the 30g. i got used to depressing the fire button on my mod before bringing it up to vape, this gave the coils just a second or two to fire before vaping. good luck
