Primarily because after having been through so many other BS’s, I fell in love with butterscotch natural the instant I tried it, and then was in Heaven when I got MF BS and combined the two. MF really stole the show, and has the lead by far though. It’s that good.
To me it was about finding the core/pure BS flavor, and then, I could mix whatever. LB ice cream, or Cap, etc…
Complex flavors are nice sometimes, but far more limiting IMO. So while I have always been curious about it (BS ripple) it was just way further down the list because of my goal, and assumption that it had an ice cream aspect which would complicate/limit uses.
I’m one who hates certain things mixed. So while most love things like cake and ice cream, or pie a la mode… I prefer them separate. Same for ice cream sandwiches. Cookies and ice cream just don’t belong together (generally speaking)! But I love cookie dough ice cream. go figure.
