The dojo that I go to teaches mixed styles but the emphasis in on goju ryu.
As for sparing we do a few different styles depending on the class level starting with slow single exchange then moving to medium contact sparing and newly started is a type of fighting that is focused solely on defense and take downs. Where it is an attacker vs. a defender, which is different from normal sparing where there can be two attackers or two defenders.
