Greetings! I have a bunch of different flavors from PA and TWEL for my Platinum Ice, and have had a time mixing and experimenting. The concentrations of the flavors are all over the place, and sometimes it takes a second or third batch to get it really A-1. So my question is, how does a guy with 20ish flavors in stock taste test while mixing? I have a nice pile of cartos dedicated to a certain flavor, but that is adding up, and I hate having 4 different cartos per flavor as I find the ultimate mix ratio. Thanks for your help!
