First of all: What kites (STD) do you fly or like?
The Black Pearl UL is a great kite. Not very easy to learn new tricks on, because slackmanagement has to be quit accurate (too much slack and you'll lose the kite). But very quick Yoyo's, good Multilazys and not too hard Tazmachines. Stable Fade. (Movie? Here:

Light kite (2PT ULE), I never got a Yofade or CrazyCopter out of it (I assume because of the light ULE).
I don't have much airtime with a JJF UL, but it a very capable kite. Smaller than a BP, but a bit more forgiving and robust.
Never flown a Ophidion.
And I won't be surprised that a Deepspace UL or a Talon UL would be recommenend on this side of the ocean. With good reason, of course.
Hope that helps,
