I picked up TFA Crunchy Cereal, on my last buying frenzy, but haven't tried it yet. It is supposed to be a plain Captain Crunch cereal type of flavor. I don't know why, but that just sounds good (as a
vape) to me. It does not appear to be nearly as popular as the Crunchy Berries.
The TFA Crunchy Berry is supposed to be the fruit version of (Captain) Crunch Berries. I hated those as a kid, so it has no appeal to me. That said; it appears to be extremely popular, with those making fruited cereal vapes (it seems to be called for in every other recipe). So, if that sounds like something you might like, then it might be worthy of a small bottle to try.
