Best citrus flavor

Hey r/hookah, as my title says, what is the best citrus flavor? I am looking for something that has a strong citrus flavor as everything that I have tried so far has not met my expectations. I have tried a few different citrus flavors as well as a few different citrus/mint flavors and they all seem to be very dull flavors, I want something strong flavored maybe even on the sour side that I can mix with a mint to get a good strong citrus mint flavor.

Currently smoking Fumari citrus/mint and I thought to ask you.
