We also use premier 700's with our C-3 and they work very nicely with it. We tested various others and liked the 700's the best. We make 3 basic size candles in our line, so ordering the 1000 is not difficult for us, plus it is really nice that we can order them to the length that we need. For all the odd sizes that we need we get them (I think) from soycandle.com. Good luck, I think you will like them if you try them. Jessica at wickit is very helpful, if you need a smaller quanitity she will help you find them from one of their distributors. I think that is why they can't offer them in smaller quanities, they are a manufacterer, not a distributor. Good luck with all of your testing. Fun, fun. fun.
