Heir Poll - Generation 6, Speed Legacy!

I'm so undecided on an heir for this generation. Each of the others had a clear favorite. :P I have my favorites for this generation, but none of them really just out at me as "the one!"

So here they are:

Percival (teen) couch potato; hates the outdoors; virtuoso; and and lucky


Leo (teen) workaholic; brave; genius; and athletic


Twins:
Chris (child) virtuoso; clumsy; and eco-friendly


Jimba (child) loves the outdoors; good; and athletic


and last, Hugo (toddler) genius and friendly
