Well I happen to have just cracked open a bottle of HV juice from there that I forgot I had coming, I love that about this stuff, it's like Christmas every other week or so. To get back on track the HV juice is designed/mixed to burn slower at high voltage. It's a bit thicker than your standard juices. It can be used in the 510 as well, in fact I think it's perfect for the manual batteries with no cutoffs since it can withstand the heat longer. As for the great Peach juice I have no clue since Peach is not a flavor I have tried. Many places carry them, the best you can do is try a few out and find the one that suits your taste. Some places I have gotten juice from and been satisfied are RockyMountainVapor.com who now are based in Michigan and offer great prices and free shipping on orders above $14 which is easy to spend. Litecigusa is another place I have gotten deals on. Of course TotallyWicked should be mentioned although I don't use them they have their fans. It's literally too big a list to name them all here, the best thing to do is go through the suppliers list and check them out. I have been to just about all of them but could not tell you what each site has.
