Taste- Not sure if my expectations were higher because I was expecting mountain dew or what, but it wasn't bad it just needed more flavor, less sugar. Not much to say about this. Its your basic mountain dew like citrus.
Buzz- 50% more of what? The little bit of taurine and caffeine you put in here? I see you didn't raise the vitamins any. 100% rda niacin. 250% vitamin B6. 80% B12 and 50% pantothenic acid.
