OK, so I got my diy supplies today, and for the most part, I'm totally happy with my flavors. I got a lot of the FA flavors that I knew I liked (liquid amber, zen garden, hypnotic mist) because I figured that would be easiest to start. I've been mixing my flavors at 10% and a few of them I ended up adding a little more to my 10mL container, but for most of my stuff, 10% seems good. However!! I have two flavors that are just blahhhh. One is fresh fig. It smells great in the bottle, but I can't taste it at all. I added more flavor, but now it's starting to taste bitter. The second flavor I'm having problems with is the cola. I think I have the strength right, but it just seems like something is missing. Kind of like when you forget to add the salt to your chocolate chip cookies. It's not bad, but it's not really good. Any tips? BTW, one of my favorite flavors so far is my imitation "malibu" with 10% coconut and 5% menthol juice I made from 50% crystals, 50% base. Any help is appreciated!
