I have a variety of flavors and filinmg to offer my customer but im not sure if having 2 many flavors a good or bad thing.

Any advice on what I can do

I have the basic: White lemon choclate red velvet strawberry etc

And many many many more like maybe 30

Should I scale it down

I think it's fun to have more flavors, especially if they are creative & different. If a customer wants something traditional, they can order it. There are plenty of people who like the fun, different flavors. Personally, I think plain chocolate & white are BORING!
