So true. You can really have fun mixing, and while we have the odd flavor master/mistress who can mix like no one's business, a little inaccuracy really isn't going to be too much of a problem. I leant a bit far towards underflavoring to start, but adding 5 or 10 drops of flavor is really easy, and isn't going to affect my nic percentage much.
My Appalachia mix has turned into one of my favorites, and the whole time I was going, "Why are you doing this? This can't possibly turn out well...." but I actually really like it now that it's steeped. The coco adds... something, and the brandy definitely cut the sweetness of forest berry. The whole time I was going, "I'm going to have to dump this whole thing."
I kind of try to approach it as fun, not deadly serious, just like I approach cooking. So far I have not found a mix that I cannot improve, except for Orange creamsicle, which I think needs... something. Not sure what yet, but the citruses are the hardest ones for me to get right..... I'm still holding fast on the no sweetener thing, but I think I may have to GET some. Sigh. It's really necessary with some flavors, and completely not with others. Can't say I understand all the science behind it, but I really enjoy it....
