I don't think there is any Spumoni or Neapolitan bike.
Most are just chocolate or vanilla, there are some chocolate/vanilla swirls, but if you want the pistachio or strawberry you have to get it separately.
Adding some dulce de leche and/or hot fudge would be an upgrade.

(See what you did Ron, talking flavors).

Since no bike does it all, getting one that better suits your needs may well be an upgrade. But just increasing bowl/scoop size isn't in itself an upgrade unless the individual perceives it as such.

In other words: It's all subjective

And if it's someone else's opinion of your sundae? Who gives a rat's @ss?
