There is a difference between the two shuffles in Dallas and in Fort Worth and the two dances are not compatible. When in one place and referng to the other city's "shuffle" you say "Dallas Shuffle" or "Fort Worth Shuffle." At Cowboys Arlington, they do the Fort Worth Shuffle most of the time. Competitive dancers in the are can be spotted doing Triple Two Step to the same music. At the Round Up, they tend to Shuffle to faster music and the dance develops a little bit of bounce or lilt as the music speeds up. Someone who is doing Triple two and someone who is doing the Dallas Shuffle can dance together, but the Dallas Shuffle is a more upright posture than the Triple Two which has more stylization and shaping to it. Now...to thoroghly confuse things, There is a dance called "Progressive Double Two" which to my eyes looks just like the Dallas Shuffle but people "in the know" insist there is a difference. *sigh* I don't see it though. All the dances are basically done to the same kind of music, but one may be slightly better than the other based on speed. The Triple Two tends to work better with the slower music, Ft Worth Shuffle with the mid-tempo and Dallas Shuffle with the Faster songs.
