I think maps like
m-flo loves CHEMISTRY - Astrosexy or
Demetori - Wind God Girl [Extra]is really dont suit for a semifinal match.
the combo of the song is really high and it is not very hard with the top players' skill.
These map is just testing the stability or focus in a match, not the real skill difference.
So I dont think that kind of map is a good choice of the match.
Maybe you can try to find some maps with lower combo and it is really need skills to win someone, like yume(by kana), Genesis of Aquarion, Anisakis, ravers fatasy(for jump), koi no honoo(for stability in moving).
