Which Floating Leaves oolong teas to gift to friend?

I'm putting together an oolong tea sampler for my friend's birthday gift. They recently got into oolong tea, so I'd like to give them a nice range to try. What are your recommendations and favorites from Floating Leaves? Thanks! :)

p.s. I specified Floating Leaves because it seems that the most popular shops are that and Mountain Stream Teas, but orders from Mountain Stream Teas won't get here in time
