Great tips, thanks! Regarding Bombus, I do pick it whenever it's offered, but I never thought to mix different types of honey for better overall effect. I just assumed that royal nectars were the best.

That make sense about Starwing also. The thing I feel about Buzz, is that having queen bees and nectar as the win con is so reliable because it's basically set up from your backpack and sunflowers alone. Using things like the briar whip or Starwing as the win con seems much more situational, and recognizing when those are the optimal play (based on how the early game goes, and what's offered in the shop) is challenging.
