Honestly, Onalaska probably sweeps again but Sauk always seems to have amazing vocals. It will be interesting to see these two matched up again after the crazyness of 2015 (when Onalaska swept the captions here and at Holmen and took 1RU to Sauk).
I am assuming they are keeping the rules the same as the last few years where Prep groups can make it to the finals and there are 7 spots (unless they follow last year and keep expanding the finals)
2nd. Chi-hi/Northern Lights (I've heard Chi-Hi is doing REALLY well this year)
These predictions are based off how these groups have done in the past and how I have heard groups are currently doing.
