I think that's more of a disad you take to get the points for tallness. You should probably buy off the disad with future xp.

I'm good - bought it off in high school/college. The build points that were supposed to go into romance languages instead went into personal kinesthetics, and I'm happy with the substitution.

If you'll notice, she's already trying to put points into tallness by adding wings to her ears.

Y'know, I don't think I've ever heard of anyone trying to pursue tallness in that particular way. It's certainly far more portable than many other methods, and potentially stylish, too.
