I agree on the Provari maintenance...when I ordered my first I went on Amazon and got the 99% alcohol and a package of really long qtips. It was pretty cheap...and makes the cleaning very easy. Have I told you all lately how much I love my KFL's..they seriously are so easy to work with. I do need to improve on my micro coil builds, but that will come with time. Mine work great..but they are not very pretty..
