These guys are playing straight, with heavy slaps and all notes at the same volume...result no swing. Sounds more like a marching band.
Why not search for Cubans playing Rumba if you want to get the real feel. Guarachon just uploaded 9 excellent videos from a great Ruma party, search for Rumba en Ateres.
Also check out Guaguanco Moperc no 2

I had the good fortune to study with Cubans in san Diego and in the Bay area for a few years and slowly beginning to get to grips with what they are putting across regarding the feel.
In a Sandy Perez, class when we are going to straight he immediately stops the whole thing and makes us start over again.
So here is an example of Guarapachangeo, #1 is by Michael Spiro who has studied with the best and played this stuff for over 30 years, a most knowledgeable and talented player and a very good teacher. #2 is by Jesus Diaz, another master.

BTW why not sign up to Congamasterclass for the introductory month and see what you think.
