more the most part you cannot just simply substitute 28g wire for 32g wire, it doesnt work like that. with 28g wire your whole set-up changes. 28g equates to low resistant vaping, you cannot use 28g if you want to vape resistances above 2 ohms , actually 28g wire is used for resistances below 1.5ish for the most part or imo lower. also imo you shouldnt use 28g with much more then 6 wraps at most on wick, for this starts to make the coils heat up to slowly becoming un-responsive. 28g shines in resistances below 1.3Ω, down to 0.6Ω, and with a mechanical mod. so its just more to it, your whole theory about vaping has to change along with your set-up to really change to 28g. for the most part a mechanical mod is best with such a thick wire, although a provari v-2 will work if done right, any other vv device has cut offs to high for the most part. provaris cut off is 0.8 compared to like 1.3 for any other vv device. if this is all confusing, and you dont quite understand this all then for now i wouldnt recommend the 28g, for you may not get the right results and will be a waste of time, utimatly trashing the 28g wire, saying that you dont understand why people say its better, when your 32g is better. but if you read up on the right ways to get the 28g working correctly and all that goes with it and expeirment on it, you will find it out performs 32g by a mile. on the other hand 30g might get you started out in the right direction first. if you have a vv device other then a provari v-2 then maybe try the 30g close to the devices cut off limit, like 1.3ohms, do this at like 4 volts and see if you perfer this to your current set-up. good luck, also with lower resistant set-ups for the 28g, your wick needs to perform better to keep up. so like i said before, you simply cannot just throw on the 28g to substitute, theres more to it for sure.
