N&K's OD was the best, but it doesn't matter so much because it was 6.0 so there was no opportunity to build a lead, unless you think D&S should not have been top 2. Both pairs had excellent blues and ok jives, but Navka's blues was just drool-worthy... that straightline.
IMO, N&K and D&S should have been 1-2 in that order in the CD/OD, so under 6.0 it would be whoever had the better FD. IMO that would be D&S because there was so much hidden difficulty in that program. The lifts were very innovative, they did sbs mirror twizzles which seemed

at the time, and they were on fire skating all out at Worlds. N&K's Pink Panther really had a lot of posing and vamping (I always say they were voguing out there a la Madonna

) and the lifts were similar to their ones from the previous year... just not enough to take the world title.
The only thing N&K had above them was the lines.... I remember Tinami posting that Albena looked like a side of beef in those lifts, which honestly is kind of true.

I think that was a legitimate critique, because a lot of people at the time said "oh D&S are just short and don't have the long legs of Navka to be able to create those lines" but in fact Albena improved tremendously in that area under Linichuk. N&K were far more polished but I don't think that alone was enough to give them the gold.
(FTR, I think N&K should've beaten D&S for bronze in 2003 and that they deserved their golds in 2005 and 2006).
