Add-on Suggestion

Hello, we are offering a bundle of products, the quantity for each product within the bundle are fixed but I want the customer to be able to choose a flavor. Here’s an example bundles.

Bundle A: $100
1 Juice (with an option to choose a 1 flavor)
3 Protein Puffs (with an option to choose a 3 different flavors)
4 Protein Bar (with an option to choose a 4 different flavors)

Bundle B: $80
2 Juice (with an option to choose a 2 flavors)
1 Protein Puffs (with an option to choose a 1 flavor)
2 Protein Bar (with an option to choose a 2 different flavors)

Again, the quantity of the products within the bundle are fixed.

Which Add-On is the best option for this setup?
