I agree with you completely. Ashley has the personality and artistic range that Gracie and Polina have yet to show. Gracie is more technically capable than she is, but Gracie has a long way to go in terms of expression (she can't just keep up the whole ice-princess thing). I also look forward to seeing Polina in the future, since she needs to grow into her body and still looks a bit awkward/coltish. As far as I'm concerned, at this point Ashley is the most promising of the U.S. ladies and I wouldn't write her off for the next quadrennial.I hope Ashley can regain her national title and get some good international results going forward. With Yuna gone and Mao possibly gone, I've actually latched onto Ashley a bit. I love how she attacks her programs and has this edge to her, rather than being some pretty ice princess. She has her own style and she knows how to sell a routine. I really hope she's the leading US lady for the next quad (sorry, I find Gracie too pageanty. Polina has potential and I like what I saw at Worlds, but she's yet to get the fire that Ashley has).
I'm not enough of a tech expert to figure out what Ashley has to do to get there, but I wish her all the best.
