Your answer has very little to do with sport and it sounds like you are describing a pageant.I think Top 6 for the Shibs is a real possibility, depending on how they skate and how others do. Where do they go from here is tough to say. I'll be very frank, there are things that will count against them and I am not going to be PC about it:
1) They will never be seen as a couple because they are brother and sister team and look way too alike, even more so than the Kerrs who can still pass for strangers, but not the Shibs
2) They still look like kids
3) They are not good looking enough in the world of Ice Dance
On Point 3, maybe they will once they mature and become adults but at this point, the lack of a handsome man + attractive woman pairing can hurt your chance in the long run - yes, looks count for a great deal in Ice Dance no matter how wrong this may sound
Am I missing something or is that really how you feel about Ice Dancing in 2011?
