Harsh and smooth is contradictory, don't you think? Polar opposites.
Higher Pg (propylene glycol ratio would result in a more harsh vape if you don't want to increase the nicotine strength.
Bobas Bounty tastes nothing like Castle Long. I have read that Gentleman's Reserve tastes similar to Castle Long.
What attracts me to Castle Long is the bourbon flavor. I currently have
Custer's Last Call from Brewmous which is a whiskey/custard flavor that is my favorite flavor.
"A creamy and indulgent flavor. Strong custard and vanilla notes that are followed by a subtle parting shot of brusk Kentucky Bourbon."
I was given a clone recipe for Castle Long if you DIY. I haven't tried it yet, but look forward to.
