Well, I guess it depends where about you are? I'm right in the middle of the UK, and most salsa seems to be on1, unless you're in Manchester or Birmingham (which are mostly on2, I think). Here in Sheffield, it's very much on1 ... I'm on1 myself, I did lessons on2 for a while, a couple of years back, and it never stuck (it felt kinda wooden and contrived). My perception, is that beginners and intermediate level dancers, tend to be on1, while advanced level, experts are tending to be on2. Is that accurate? Thanks.
