I have a bunch of DIY stuff that I have yet to find time to really try much of. I will certainly share when I have somthing of worth to add here...
I really just wanted to second that you should sample some of Drew's Juices from Nhaler. There is a huge difference in how Drew's HV
juice holds up at HV by comparison. His regular
juice seems to hold up better than most standard DK and KR juices. I suggest this so you have a "benchmark" if you will for testing your own mixes and some clues about what a good HV mix is like.
