There are a few Latin styles that I need:

Modern Bachata (Adventura style)
Raggaeton
Modern Merengue (Suavemente, Mi Nina Bonita)
Salsa (both 3/2 and 2/3 clave variations)
Cumbia Mexicana (Grupo Limite)
Cumbia Moderna (Kumbia Kings)
A traditional 50's Cuban cha cha cha ( no drum set, and quater note cha cha bell, guiero, and congas)

Trio Style (like Los Ponchos with some lite maracas and bongos)

50's 12/8 (Earth Angel, Donna, Put your head on my shoulders)

Country 12/8 (Crazy)

Swing with a simple quarter note guitar (Freddie Green/Count Bassie)

I agree with Scott Lee about jazz brush styles!

How about a bossanova brush/stick?

Also I haven't heard a really good 60's Jobim style bossa.
