Ooo Gav now there's a leading question......
A potted history
The Lindy Circle - Lindy Hop History
What people perceive as smooth is usually based on Hollywood, "bouncy" is Savoy. HOWEVER good Savoy style dancers don't really bounce - watch their heads not their feet
It's worth noting that when Lindy became popular again there were great debates over what was the best style leading to a bit of a polarisation of the community into 2 camps - bonkers really & some of the nasty stuff that was said on the Interweb is still there to be found.
Other forms of dance are out there in the UK called Lindy that pure Savoy style or Hollywood style advocates would describe as heretical but that's kind of missing the point - Lindy is essentially about Lead and Follow within the confines of the 6 & 8 count rhythm. If you understand how the lead works and how the rhythm works then which "style" you "do" doesn't matter.
Hope you stick with it
